Chapter 12.3, Problem 2WE

To determine

To calculate: The lateral area, total area, and volume of each solid.

Answer to Problem 2WE

The lateral area = 703.36 sq. units, total area = 904.32 sq. units, and volume = 2009.6 cu. units

Explanation of Solution

Given information: Consider the given information,

Radius = 8units, Height = 10units, $\pi \approx 3.14$

Formula used: Consider the given formula,

r = radius, h = height

Lateral area = $2\pi rh+\pi r^2$

Total area = $2\pi rh+2\pi r^2$

Volume = $\pi r^{2}h$

Calculation : The following category can be reduced to,

Lateral area = $(2\times 3.14\times 8\times 10)+(3.14\times 64)=703.36$ sq. units

Total area = $(2\times 3.14\times 8\times 10)+(2\times 3.14\times 64)=904.32$ sq. units

Volume = $3.14\times 64\times 10=2009.6$ cu. units
