The area (A) of a circle with radius r is given by
... A = π·r²
For a radius of 7 ft, the area is
... A = π·(7 ft)² = 49π ft² ≈ 154 ft²
The area of the bottom of a circular tent with radius 7 ft is about 154 ft².

Answer:
The angle is 90 degrees
Step-by-step explanation:
Required
Angle subtended by the diameter
The theorem to solve this is:
The angle subtended by an arc is twice the angle it subtends.
