Chapter 12.9, Problem 5IP

To determine

To find : Lateral and

Answer to Problem 5IP

LSA = $38.94{\text{ yd}}^{\text{2}}$ and SA = $99.29{\text{yd}}^{\text{2}}$

Explanation of Solution

Given information :

The given information is, radius = $3.1$ yd and height = $2$ yd

  

Formula Used:

Lateral Surface Area (LSA) = $2\pi rh$

Surface Area (SA) = $2\pi rh+2\pi r^2$

Calculation :

Lateral Surface Area = $2\times (3.14)\times (3.1)(2)=38.98{\text{ yd}}^{\text{2}}$

Surface Area (SA) = $38.94+2\times 3.14{(3.1)}^2$

  $\begin{array}{l}=38.94+60.35\\ =99.29{\text{yd}}^{\text{2}}\end{array}$
