The formula for the area of a circle is
π times radius ^ 2
You can use 3.14 for the value of Pi (π)
So, in your case the calculation is:
3.14 x 70 x 70 = 15,386
Since your radius was measured in feet, the answer is in square feet.
15, 386 sq. ft.
The formula of area of circle is pi r^2. You can use 22/7, 3.14 or calculator pi for your answer. It's up to you to choose
The final answer would be:
area of circle: 3.142*70^2= 15, 386 square feet
the formula is π x radius ^ 2
π = 3.14
3.14 x 70^2 = 15,386
