Find the total surface area of this cylinder . Give your answer to 1 decimal place 7cm 15 cm
Leto [7]

Answer:

Step-by-step explanation:

r = 7 cm

h = 15cm

pi = 3.14

Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).

Area = 2* pi *r^2 = 2 * 3.14 * 7^2

Area = 2 * 3.14 * 49

Area =                                                        307.72  Don't round this.

Cylinder body

Cylinder body = Circumference * h = 2*pi * r * h

Cylinder body = 2* 3.14 * 7 * 15

Cylinder body =                                      <u> 659.4</u>

<u />

Total =                                                      967.12

Rounded        967.1     Answer
