Question

area of a circle is 75. 46 cm find its diameter with

Answer 1

HEY MATE HERE IS YOUR ANSWER

Area of circle =
$\pi {r}^{2}$
Area of circle = 75.46cm
$\pi {r}^{2} = 75.46 \\ \frac{22}{7} {r}^{2} = 75.46cm \\ \\ \frac{11}{7} {r}^{2} = 6.86 \\ \\ {r}^{2} = 4.3654545455 \\ r = 2.0893670203$
2r=diameter
diameter = 2 (2.0893670203)
diameter = 4.178740406
