Question

A cylinder net is shown and the height is 10 inches high and has a radius of 2 inches. what is the surface area? Let π = 3.14.

a) 25 in2

b) 126 in2

c) 151 in2

d) 302 in2

Answer 1

Answer:

C

Step-by-step explanation:

find the area of the circles on the top and bottom with area of a circle being pie r squared

$2(\pi 2^{2} )$=25.12

Find the area of the rectangle, with the height being one side and the circumference of the circle being the other

$(2\pi (2)) 10=125.6$

add the two together to get 150.72 and round
