Question

Find the exact area of a circle with the given circumference 3 pi

Answer 1

Oh so we have thw circumference
And in order to find the area we will need to find the radius
So
Circumstance = 2 * pi * r
We have the Circumstance equal to 3pi so
3pi = 2 * pi * r
Can you solve for r
We need ro find the radius So that we can use it in the formula
Area = pi * r^2

Answer 2

Would the answer be 12.56

Answer 3

i think you are not correct.
\[2 \pi r=3 \pi,r=\frac{ 3 \pi }{ 2 \pi }=\frac{ 3 }{ 2 },r^2=\left( \frac{ 3 }{ 2 } \right)^2=\frac{ 9 }{ 4 }\]
\[area=\pi r^2=\frac{ 22 }{ 7 }\times \frac{ 9 }{ 4 }=\frac{ 99 }{ 14 }=....\]

Answer 4

How much did you get for the radius

Answer 5

4

Answer 6

That's wrong

Answer 7

What should it be
