Question

If the perimeter and area of a circle are numerically equal then find the diameter of the circle

Answer 1

$\huge \colorbox{black}{{ \color{white}{4 Units}}}$

Area of the circle = Perimeter of the circle

πr² = 2πr

r²/r = 2π/π

r = 2 units

2 x radius = diameter

Therefore, diameter = 2 x 2 = 4 units
