The circumference of a circle is 5 Pi cm. What is the area of the circle?
2 answers:
Answer:
6.25
or and estimated answer of 19.625
Step-by-step explanation:
C = 2R
Since 2R = D, the diameter is 5 cm and the radius is 2.5 cm
(D = diameter) (R = radius)
The area of a circle is 

So 2.5 squared equals 6.25
The area of this circle is 6.25
or and estimated answer of 19.625
(6.25 times pi)
Answer:
6.25 pi cm^2
Step-by-step explanation:
The formula for circumference is
C = 2*pi*r
We know the circumference is 5 pi
5 pi = 2 * pi *r
Divide each side by pi
5 pi/pi = 2 * pi *r/pi
5 = 2r
Divide by 2
5/2 = 2r/2
2.5 = r
We need to find the area of the circle
The area is given by
A = pi * r^2
= pi * (2/5)^2
= pi *6.25
= 6.25 pi cm^2

Answer:
A
Step-by-step explanation:
Given
5(x - 7) = 55, then using the distributive property, that is
a(b - c) = ab - ac, then
5x - 35 = 55
