Find the area of the larger circle if the circumference of one of the smaller circles is 36 pi mm. class=

Verified Answer :

C ( smaller ) = 36 π mm
2 r π = 36 π  / : π
2 r = 18 mm
Radius of the larger circle: r = 2 · 18 = 36 mm
A = r² π = 36² π = 1296 π mm²
Answer: area of the larger circle is 1296 π mm².

Answer:

The area of the larger circle is 4069.44 millimeter square.

Step-by-step explanation:

Given : The circumference of one of the smaller circles is 36 pi mm.

To find : The area of the larger circle?

Solution :

Circumference of the smaller circle is \(C=36\pi\)

Circumference of circle is \(C=2\pi r\)

Substitute the value,

\(36\pi=2\pi r\)

\(r=18\)

The radius of smaller circle is 18 mm.

The radius of larger circle is twice the radius of smaller circle.

Radius of the larger circle, R= 2(r)=2(18)=36 mm  

Area of the larger circle is \(A=\pi R^2\)

\(A=\pi 36^2\)

\(A=1296\pi\)

\(A=4069.44mm^2\)

Therefore, The area of the larger circle is 4069.44 millimeter square.
