1) Since 8 is 3 units away from 5 we know the radius is 3. When we put that in the circumference formula we get 6(pi) which is 18.8

2) When we use pythagorean thereom we get that the radius is 5 time the square root of 2. When we put this in the area formula we get 25(2)(pi) which is 157.1

The formula for the volume of a right circular cone is shown. Rewrite the formula so that it expresses the height h in terms of

zlopas [31]

Height of cone in term of volume is 3V / πr²

Given that;

Volume of cone = (1/3)(πr²h)

Find:

Height of cone

Computation:

We know that;

Volume of cone = (1/3)(πr²h)

We have to calculate height from above given formula.

V = (1/3)(πr²h)

3V = πr²h

3V / πr² = h

So,

Height of cone = 3V / πr²

Height of cone in term of volume = 3V / πr²

How many times greater is the value of the 4 in 640,700 than the value of the 4 in 67,040

Dafna1 [17]

640,700 :- the four in this number is 40,000
67,040 :- the four in this number is 40

Now, we need to find out how many times greater 40,000 is than 40.

40,000/40 = 1000

Answer: It is 1000 times greater.
