Question

find the circumference and the area of a circle of diameter 49

Answer 1

circumference of circle =2πr
so, r= 49÷2 = 24.5
and π=3.14
circumference= 2×3.14×24.5
=153.86
and area =πr^2.
=3.14×24.5×24.5
=1884.785

Answer 2

Diameter = 49 m

r = 49/2 m

Circumference = 2πr

=> 2×22/7×49/2

=> 154 m

Area of circle = πr²

=> (22/7*49/2*49/2 )

=> 1886.5 m²
