Find the missing measure for a right circular cone given the following information. Find h if r = 5 and V = 100. 4 12 30
Blizzard [7]
-------------------------------------------------
Volume of cone:
-------------------------------------------------
Volume = 1/3 πr²h

-------------------------------------------------
Find Height:
-------------------------------------------------
Given that the radius = 5 and the volume = 100, we will substitute these values into their respective variable and solve for height.

Volume = 1/3 πr²h
100 = 1/3 π (5)²h
h = 100 ÷ 1/3π(25)
h= 4 units (Nearest whole number)

-------------------------------------------------
Answer: The height is 4 units.

It takes Emma 3/4 minutes to ride her bike a distance of 1/8 miles. What is Emma's average speed in miles per minute?
sp2606 [1]

Answer:

The answer is 1/6

Step-by-step explanation:

1/8 miles in 3/4 minutes

then, that means in 1 minute ( 1 min = 3/4 * 4/3) Emma will ride a distance of (1/8)*(4/3)= (1*4)/(8*3)= 1/6.

The answer is 1/6 (in 1 min she will ride 1/6 miles).

Hope that useful for you.
