Hint: In the question we are asked to find the area of a circle with given radius. For this we must know the formula of circle i.e. . The formula is simple and only needs the radius of the circle to find its area.
Complete step-by-step answer:
Here, to find the area of the circle, we must know the formula of the circle. The formula to find the area of a circle is .
Where, A is the area of the circle,
is the constant ratio of circumference of a circle,
‘r’ is the variable representing the radius of the circle which is the distance from the centre outward.
From the question, we know that –
Here, we will substitute the value of radius in the formula of area of the square.
Hence, the area of the circle with the radius 5cm is
Note: Area of a circle is the region occupied by the circle in a two dimensional plane. It can be determined easily using a formula, . In the solution, we can also use the value of as 3.14. This area formula is useful for measuring the space occupied by a circular field or a plot. Suppose, if you have the plot to fence it, then the area formula will help you to check how much fencing is required.
