The diameter of circle is 10.0 feet.
We are given the area of circle. The formula of area with respect to diameter is as follows -
Area = 1/4πd², where d represents diameter of circle.
Taking the value of π as 3.14.
Rewriting the equation according to diameter -
d² = (area×4)÷π
Now, keep the values in formula to find the diameter of circle.
d² = (79×4)÷3.14
Performing multiplication on the Right hand side of the equation
d² = 316÷3.14
Performing division on the Right hand side of the equation
d² = 100.6
d = √100.6
Taking square root on the Right hand side of the equation
d = 10.03 feet
Rounding to nearest tenth -
d = 10.0 feet
Hence, the diameter of circle is 10.0 feet.
