Answer:
A = 64 pi
or approximately 200.96
Step-by-step explanation:
The diameter is twice the radius
d = 2r
16 = 2r
Divide by 2
16/2 = 2r/2
8 =r
The area of a circle is
A = pi *r^2
A = pi*(8)^2
= pi *64
Or if we approximate pi as 3.14
A = (3.14) * (64)
A = 200.96
Answer:
Step-by-step explanation:
W=2.5, L=x
A=LW=2.5x
P=2(L+W)=2(2.5+x)=5+2x
P=A
5+2x=2.5x
5-0.5x=0
-0.5x=-5
x=10
