Question

The diameter of a circle is 6 m. Find its area in terms of π π.

Answer 1

Area of circle = πr ²
Radius is half on diameter =6/2=3m
π(3²)=9πm²

Answer 2

Step-by-step explanation:

this is totally simple.

the formula for the area of a circle (as you can find with any search on the internet in seconds) :

A = pi×r²

r is the radius.

and once you understand even the most basics of a circle, you know that the radius is half of the diameter.

so, in our case, r = 6/2 = 3 m

the area of the circle is therefore

pi×r² = pi×3² = pi×9 m²
