Verified Answer :

Circumference of a circle:
C = 2 r π 
10 = 2 r π
r = 10 / 2π = 5 / π
Area of a circle:
A = r² π = ( 5 / π )² π = 25 / π²  π = 25 / π ≠ 100
Answer: False.

Answer:

False

Step-by-step explanation:

Circumference(C) and Area(A) of the circle is given by:

\(C = 2 \pi r\)

\(A = \pi r^2\)

where, r is the radius of the circle.

As per the statement:

A circle with circumference of 10 has area of 100.

Circumference = 10 units

then;

\(2 \pi r = 10\)

Divide both sides by \(2 \pi\) we have;

\(r = \frac{5}{\pi}\) units

Find area of circle:

\(A = \pi r^2\)

Substitute the value of r we have;

\(A = \pi \cdot (\frac{5}{\pi})^2\)

⇒\(A = \pi \cdot \frac{25}{\pi^2} = \frac{25}{\pi}\)

But A = 100 square units

⇒\(A = \frac{25}{\pi} eq 100\)

Therefore, the given statement is FALSE
