Find the surface area of this cylinder. Round to the nearest tenth.

r = 3 cm
3 cm
SA = [ ? ] cm2

PLEASE HELP

Formula for the surface area of a cylinder: 2 x pi x r^2 + 2 x pi x r x h

Radius (r) = 3

Height (h) = 3

2 x pi x 3^2 + 2 x pi x 3 x 3

2 x pi x 9 + 2 x pi x 9

18pi + 18pi

36pi = 113.1 cm^2

Hope this helps!

113.1

Step-by-step explanation:

2πrh + 2πr^2

2 * π * 3*3 + 2π*3^2

= 113.097

round it to 113.1

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
