Question

Label the net for the cylinder. Then find the surface area of the cylinder. Give your answer in term of π and as a decimal number rounded to the nearest tenth.
Question 2
Surface Area:
π≈
ft2
DO NOT PUT RANDOM ANSWERS!!!!!!!!!

Answer 1

To find the surface area of a cylinder, add the areas of the two circles and the rectangular piece connecting them

area of circle: A = pi(r)^2
A = pi(7)^2
A = 49pi

area of rectangle: A = length X width
the length is the circumference of the circle
C = 2pi(r)
C = 2pi(7)
C = 14pi
multiply 14 pi by the width 5
area of rectangle: 70pi

add the areas of the two circles and the rectangle:
49pi + 49pi + 70pi = 168pi

ANSWER: 168pi
for the decimal if you use pi on the calculator then the answer is 527.8
but if u multiply by 3.14 the answer is 527.5

hope this helps!
