Question

I forgot how to solve this can someone explain please

Answer 1

Answer:

radius = 14 in

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here V = 196π and h = 1, thus

πr² × 1 = 196π ( divide both sides by π )

r² = 196 ( take the square root of both sides )

r = $\sqrt{196}$ = 14

Answer 2

Answer:

The radius of cylinder is 14 inches

Step-by-step explanation:

Given that the volume of cylinder is 196π in² and the height is 1 in . The formula for it is V = πr²h. Then you can substitute the following value into the formula:

V = 196π

h = 1

196π = π × r² × 1

r² = 196π/π

r² = 196

r = 14 in
