Question

Area of two circular sheets are 84 aqm and 70 sqm find the circumference of a third sheet whose area is equal to the total area of first two sheets

Answer 1

area of new sheet =84+70=154
area of new sheet =πr2
154*7/22=r2
r=7
circumference of new sheet=2πr
=2*22/7*7
=44cm
hope it ll help ya'all

Answer 2

The circumference of a third sheet whose area is equal to the total area of first two sheets is 44 m

Step-by-step explanation:

Area of 1st circular sheet = 84

Area of 2nd circular sheet = 70

Area of third circular sheet is equal to the total area of first two sheets

Area of third circular sheet = 84+70=154 sq.m.

Area of circle =$\pi r^2$

Sop,$\pi r^2 = 154$

$\frac{22}{7}r^2=154$

$r=\sqrt{\frac{154 \times 7}{22}}$

r=7

Circumference of third circle = $2 \pi r = 2 \times \frac{22}{7} \times 7 = 44 m$

Hence the circumference of a third sheet whose area is equal to the total area of first two sheets is 44 m
