Answer:
314.2ft^2
Step-by-step explanation:
Given data
Diameter= 20ft
Radius r= 20/2= 10ft
The expression for the area is
A= πr^2
A= 3.142*10^2
A= 3.142*100
A= 314.2ft^2
Hence the area is 314.2ft^2
Answer:
A) -292.5
Step-by-step explanation:
-65 x 9 = -585
-585 ÷ 2 = -292.5
So for this function we will be using the quadratic formula, which is
, to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:

In short, your x-intercepts (rounded to the hundredths) are (1.92,0) and (-3.92,0).
