Question

surface area of cylinders quick check
find the surface area of a cylinder with a radius of 5 inches and a height of 10 inches. use the approximation 3.14 for pi. (1 point)
471 square inches
471 inches
345.4 square inches
314 square inches

Explanation:

Step1: Recall surface area formula

The total surface area of a cylinder is $SA = 2\pi r^2 + 2\pi r h$, where $r$ is radius, $h$ is height.

Step2: Substitute given values

$r=5$, $h=10$, $\pi=3.14$
First calculate $2\pi r^2$:
$2\times3.14\times5^2 = 2\times3.14\times25 = 157$
Then calculate $2\pi r h$:
$2\times3.14\times5\times10 = 314$

Step3: Sum the two parts

$SA = 157 + 314 = 471$

Answer:

471 square inches
