The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.
The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.
The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:
2π(5/4)^2 = 25/2 π square centimeters
The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:
2π(5/4)(15/4) = 75/2 π square centimeters
Therefore, the total surface area of the cylinder is:
25/2 π + 75/2 π = 100/2 π = 50 π square centimeters
So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

A pattern of triangular numbers is shown. The first is 1, the second is 3, the third is 6, and so on. The formula 0.5n2 + 0.5n can be used to find the nth triangular number. Is 50 a triangular number? Explain.
(picture)
Answer:
50 is not a triangular number
Step-by-step explanation:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 =55
The way to calculate triangle numbers is to add the corresponding number.
For example, 1 is a triangle 1 + 2 is a triangle 1 + 2 + 3 is a triangle so on and so forth.
Triangle numbers would be 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, and 91

What is the area of this trapezoid?
Enter your answer in the box.
Answer:
153 units squared
Step-by-step explanation:
first, multiply 10 x9 to find the area of the rectangle, which is 90
then find the area of the triangle. The formula for area of a triangle is
A=1/2bh
so, 7 x 9= 63 divided by 2 is 31.5
since there are 2, multiply 31.5 x 2= 63
add 63 to 90 which is 153
Answer: 153 sq. units
Step-by-step explanation:
Base a = 10
Base b = 7x2 = 24
Height = 9
area of trapezoid = 1/2 * (a+b) * h
= 10+24 * 9 /2
= 306/2 = 153

Angelica’s speed is 4 cm/minute, Monique’s speed is 3. 5 cm/minute, and Courtney’s speed is 5. 5 cm/minute. Which turtle will win the race? Explain your reasoning.
Answer:
C O U R T N E Y
Step-by-step explanation:
Look at their speed… meaning;
Angelica can run 4 cm per minute
Monique can run 3.5 cm per minute
And Courtney can run 5.5 cm per minute
The longest one is the fastest one
It says “per minute (/minute) which means courtney will win he can run to 5.5 cm in just a minute, but the others is slower than her

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a diameter of 16 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?
Use 3.14 for pi, and do not round your answer.
The total cost of the nickel for the sculpture is $12,660.48.
We know that the volume of a cone is:
v = 1/3πr²h ......(i)
where r ⇒ radius of the cone
h ⇒ height of the cone
Now, as per the question,
r = diameter/2 = 16÷2 = 8 inches
h = 84 inches
Putting the values in equation (i)
v = 1/3 × 3.14 × (8)² × 84
v = 5626.88 cubic inch
The cost given for nickel = $2.25 per cubic inch
So, the total cost for the nickel used in making the sculpture:
the volume of cone × cost per cubic inch
5626.88 × 2.25 = $12,660.48
Therefore, the total cost for the nickel used is $12,660.48

Answer:
factor it and see if one of those factors is x − 8 x-8 x−8 ...
Step-by-step explanation:
Therefore, if the quadratic equation has a solution of 8, then it must have a factor of. Since x − 8 x-8 x−8 must be a factor of any quadratic equation that has a solution of 8, the first way you could determine if a quadratic equation has a solution of 8 is to

Which expression represents the sum of 2/3m - 1 1/6 and 5/6m - 1 1/3?
HOW DO I DO THIS??????
Answer:
-m+15/6
2/3m-5/3m-5/2
Answer: 1 5/6m - 2 1/2
Step-by-step explanation:
(2/3m - 1 1/6) + (5/6m - 1 1/3)
2/3m X 2 = 4/6m
4/6m + 5/6m = 11/6m=1 5/6m
-1 1/3 X 2 = -1 2/6
-1 2/6 - 1 1/6 = -2 1/2

Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.
Answer: 37.5%
