A cone's height is equal to the radius of its base. The area of its base is 1,386 square units. The approximate radius of the co
ne's base is____ units. The approximate volume of the cone is ____cubic units. Use . Pie= 22/7
1 answer:
Answer:
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

Answer:
![5x\leq30](https://tex.z-dn.net/?f=5x%5Cleq30)
Step-by-step explanation:
Let
x -----> the number of ice cream
we know that
![5x\leq30](https://tex.z-dn.net/?f=5x%5Cleq30)
Solve for x
Divide by 5 both sides
![x\leq30/5](https://tex.z-dn.net/?f=x%5Cleq30%2F5)
![x\leq 6\ ice\ cream](https://tex.z-dn.net/?f=x%5Cleq%206%5C%20ice%5C%20cream)
therefore
The maximum number of ice cream is 6
The answer is around 79, but if you want to round it, you could round it up to 80.
