Question

Find area of the circle whose diameter is 5 cm?
(a) 19.64 cm (b) 18.64 cm
(c) 17.64 cm
(d) 16,64 cm​

Answer 1

hey mate!

Diameter = 5cm

so, radius = 5/2 cm

Area of circle = $\pi r^{2} \\= \frac{22}{7} * \frac{5}{2}*\frac{5}{2} \\= \frac{275}{14} = 19.64 cm^{2}$

So, Option A is the answer
