Question

find the area of a circle whose radius is 2.5 CM

Answer 1

2πr=2×22/7×2.5
=15.7142857

Answer 2

Concept Introduction:

Area of circle is measured by formula $\pi r^{2}$ where r is radius of circle.

Given: Radius of circle is $2.5cm$.

To Find:

We have to find the value of, area of a circle.

Solution:

According to the problem,

Radius of circle is $2.5cm$.

Therefore area of circle is $\pi r^{2} = 3.14*2.5*2.5=19.625$$cm^{2}$.

Final Answer:

The value of area of circle is $19.625cm^2$.
