Answer:

Area = 154 m^2

Circumference = 44m

Step-by-step explanation:

We know, that circumference= [tex]2\pi r[/tex]

Given, Radius = 7m

So with the given information, we can find the circumference,

=> [tex]2\pi r[/tex] = C (C = Circumference)

=> 2 * 22/7 * 7

=> 2 * 22 (As 7 and 7 cancel each other out)

=> 44m

Therefore, cricumference = 44m

It's is also given it find area of the circle

Area = A = [tex]\pi r^{2}[/tex]

=> [tex]\pi r^{2}[/tex] = A

=> 22/7 * 7 * 7 (as 7 = radius)

=> 22 * 7 (as 7 and 7 cancel each other out)

=> 154m^2

Therefore, know we know the Area as well,

Area = 154 m^2

Circumference = 44m
