Answer :
The area of a circle is pi times the radius squared; (A = π r²)
If the diameter is 3.12, then the radius is: r = 1.56.
So, the area will be:
A = π r²
A = π x (1.56)² = 7.64
The area of a circle is pi times the radius squared; (A = π r²)
If the diameter is 3.12, then the radius is: r = 1.56.
So, the area will be:
A = π r²
A = π x (1.56)² = 7.64
