Step-by-step explanation:
If the radius is 7p sqrt of 7p and you have your answer
The area of a circle is pi times the radius squared (A = π r²)
The value of the given expression is 
Solution:
Given expression is
.
Let us first convert mixed fraction into improper fraction.

Substitute this in the given expression.


To simplify the above expression, 21 and 60 are cancelled by 3.

Do cross multiplication to make the denominator same.

Answer:
The function of height has a maximum value.
Step-by-step explanation:
Maximum or Minimum:
A given function f(x).
- Find out f'(x) and f''(x)
- Then set f'(x)=0 which gives x=a.
- f''(a) > 0 , then at x=a , f(x) has minimum value.
- If f''(a)<0 , then at x=a, f(x) has maximum value.
Given that, a baseball is thrown with with an velocity of 32 feet per second.
The equation of height is

Differentiating with respect to t

Again differentiating with respect to t

Next, we set h'=0



Now 
Since at t=1, h''<0.
The function of height has a maximum value.
The maximum of h is = -16.(1)²+32
= -16+32
=16 feet
