Answer:
81 π / 254.469004941 ft²
Step-by-step explanation:
Area of circle = π × r²
Half the diameter = radius
18 ft ÷ 2 = 9 ft
9 ft = radius
Area of circle = π × 9²
Area of circle = 81π
Area of circle = 81 π / 254.469004941
Area of circle =
<span>To rephrase the question,
17% of what is $51?
Let me give you a short way or formula.
is/of = %/100
is = 51
0f = x
%= 17%
51/x = 17/100
51*100 = x*17
5100= 17x
5100/17= x
so x = 300</span>
