Answer 1

Answer:

Circumference = 2 x 3.14 x radius = 27 (in)

=> radius = 27/(2 x 3.14) = 4.3 (in)

=> Area = 3.14 x radius^2 = 3.14 x 4.3^2 = 58.1 (in2)

Answer 2

Answer:

58 inches^2

Step-by-step explanation:

The formula for the area of a circle is $\pi *radius^{2}$

To work out the area of this circle you would first need to divide the circumference of 27 by pi, this gives you 8.594. This is because the formula for the circumference is: $\pi *diameter$ and so by dividing the circumference by pi we are isolating the value of the diameter.

Then now that we have worked out the diameter we can now begin to work out the area, however in order to work out the area we must work out the radius. You can do this by dividing the diameter by 2, which gives you 4.297.

Then to work out the area you would multiply pi by the radius of 4.297 squared, this gives you 58.01 $inches^{2}$.

The next step is to round it to the nearest whole number, this gives you 58.

1) Divide 27 by pi.

$27/\pi =8.594$

2) Divide 8.594 by 2.

$8.594/2=4.297$

3) Multiply pi by 4.297 squared.

$\pi *4.297^{2} =58.01$

4) Round to the nearest whole number.

58 square inches
