<h2>288 ft³</h2>Step-by-step explanation:
The formula of a volume of a prism:
where
<em>B</em><em> - area of a base</em>
<em>H</em><em> - height of a prism</em>
<em />
In the base we have the right treiangle. The formula of an area of a right triangle is:
where
<em>a, b</em><em> - are legs</em>
We have

Answer:
Approximate radius of the given hemisphere is 3 in.
Step-by-step explanation:
Formula to calculate the volume of a hemisphere is given by,
V =
Since, volume of the given hemisphere in the picture = 56.52 in²
By substituting the value of V in the formula,
56.52 =
Now solve the expression for the value of 'r',
r³ =
r³ = 26.99
r = ∛(26.99)
r = 3 in.
Therefore, approximate radius of the given hemisphere is 3 in.
