Answer:

we have to find equalent

Answer 2

Given,

The diameter of the circle = 7 cm

To find,

The area of the given circle.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Radius of the circle = 7/2 = 3.5 cm

(Because, the value of the radius is needed to be applied in the formula of the area of a circle.)

Now, we have to apply the area of the circle formula.

Area of the circle = 22/7 × (3.5)² = 38.5 cm²

(This is the final result of the area of the circle.)

Hence, the area of the given circle is 38.5 cm².
