Question

find the area of a circle using Pi equals to 3 1/7

Answer 1

heya!

$given \: diameter \: of \: the \: circle \: is \: 2\frac{5}{2} \\ = \frac{14}{5} \\ = 2.8\\ \\ therefore \: radius \: will \: be = \frac{2.8}{2} \\ = 1.4 \\ \\ \pi \: is \: given \: 3 \frac{1}{7} \\ = \frac{22}{7} \\ \\ hence \: area \: of \: the \: circle = \pi {r}^{2} \\ = \frac{22}{7} \times 1.4 \times 1.4 \\ = \frac{43.12}{7} \\ = 6.16unit^{2} \\ \\ hope \: this \: helps \: u...$
