Question

If the area of a circle is numerically equal to twice its circumference, then the diameter of the circle is

Answer 1

let circumference = x

2x + x = circle

Answer 2

$\huge\underline{Solution}$

Let the area of a circle = r

Area of a circle = 2 Circumference

$\pi {r}^{2} = 2 \times2\pi \: r \\ \\ \frac{ {r}^{2} }{r} = \frac{4\pi}{\pi} \\ \\ now \: after \: solving \: = r = 4$

Diameter = 2r

(Put the value of r = 4)

Diameter = 2 × 4

Diameter = 8 unit
