Step-by-step explanation:
Solution,
Diameter (d)= 30 ft
Therefore,
Radius(r)= d/2= 30ft/2 = 15ft
We know that,
Area of circle is given by:-
[tex]\pi {r}^{2} \\ \frac{22}{7} \times ({15})^{2} \\ \frac{22}{7} \times 15 \times 15 \\ \frac{4950}{7} \\ 707.143[/tex]
Hence, the area of given circle is 707.143 ft²
