I want to know the answer and steps please I would appreciate it.

Answer 1

ANSWER

$578.05yd^2$

EXPLANATION

Given;

$\begin{gathered} diameter(d)=8yd \\ radius(r)=\frac{d}{2}=\frac{8}{2}=4 \\ height(h)=19yd \end{gathered}$

Recall, the formula for finding the surface area of a cylinder is;

$A=2\pi rh+2\pi r^2$

Substituting the values;

$\begin{gathered} A=2\pi rh+2\pi r^2 \\ =2\times3.14\times4\times19+2\times3.14\times4^2 \\ =477.28+100.48 \\ =578.05 \end{gathered}$
