Question

Find the area of the circle whose diameter is 1.4m​

Answer 1

r=d÷2=1.4÷2=0.7m

area=

$\pi \times r \times r$

22÷7×0.7×0.7

Answer 2

THE AREA OF CIRCLE IS GIVEN AS

                          πr²

here ,we have diameter d=1.4 m

                            d=2r

                            r=d/2

                           r=1.4/2

                           r=0.7m

for area,  πr²=3.14×[0.7]²=3.14×0.49= 1.5386 m²
