Question

what is the surface area of this cylinder ?q​

Answer 1

Answer:

130 pi or 408.41

Step-by-step explanation:

formula for sa of a cylinder is 2pir^2+2pirh

you just fill in the r and h

Answer 2

Answer:

$\approx 408.2$ in²

Step-by-step explanation:

The surface area of a cylinder can be represented as $2\pi rh+2\pi r2$. Let's represent pi as 3.14 and r is 5 and h is 8.

$(2\cdot 3.14\cdot 5\cdot8) + (2\cdot 3.14 \cdot 5^2)\\\\251.2 + 157 = 408.2$

This means the surface area of this cylinder is 408.2 in².

Hope this helped!
