A comes height is equal to the radius of its base. The area of its base is 1386 square units. The approximate radius of the cone
s base is ___ units. The approximate volume of the cone is ___ civic units. Use pi=22/7
1 answer:
Answer:
Radius = 21 units
Volume = 9702 units³
Step-by-step explanation:
The area of the base is given by the formula ... A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
The volume is given by ...V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 cubic units
