What is the value of the radius of the following circle with an area of 154 cm2?
Solution:
It is given that
Area of the circle = 154 cm2 … (1)
We know that
Area of the circle is given by π r2 …. (2)
Where r is the radius
By equating both
π r2 = 154
So we get
r2 = 154 / π
On considering value of π as 22/7, we get
r2 = 49
Taking square root on the other side
r = 7 cm
Therefore, the value of the radius is 7 cm.
What is the value of the radius of the following circle with an area of 154 cm2?
Summary:
The value of the radius of the following circle with an area of 154 cm2 is 7 cm.
