Question

I’m confused can someone help and answer?

Answer 1

Just plug in the radius (5 in) for the 2 r's in your equation and the height (30 in) for the h in your equation.

SA=(2×3.14×5^2)+(2×3.14×5×30)
SS=(2×3.14×25)+(2×3.14×5×30)
SA=157+942
SA=1099 sq inches

Answer 2

The radius is 5 inches, so r = 5
The height is 30 inches, so h = 30
We'll use pi = 3.14

Plug in the given values and then use PEMDAS to simplify
SA = Surface Area
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*5^2 + 2*3.14*5*30
SA = 2*3.14*25 + 2*3.14*5*30
SA = 6.28*25 + 6.28*150
SA = 157 + 942
SA = 1099

Answer: 1099
