Solution

Formula: 1 Mark
Answer: 1 Mark

Given that
The diameter of a circle is 10m.
Area of the circle whose radius is R is $π \times (R)^{2}$

Radius of the given circle = $\frac{10}{2}$

= 5m

Area of the given circle = $π \times (5)^{2}$

= 78.5 $m^{2}$

= 785000 ${c m}^{2}$

Area of the required circle is 785000 ${c m}^{2}$
