Answer:
A = 201.0 mi^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know that r = 8
A = (3.14) *8^2
A = 3.14 * 64
A = 200.96 mi ^2
Rounding to the nearest tenth
A = 201.0 mi^2
Answer:
201.1 mi
Step-by-step explanation:
1. Use the formula for area of a circle which is A=pi r^2
2. Plug in 8 for r (representing the radius):
8^2= 64 x pi = 201.1

Answer:
x=104
Step-by-step explanation:
2/5(x-4)=20
2/5x-8/5=20
