Answer:

  37.35 in

Step-by-step explanation:

The volume of a cone is given by the formula ...

  V = (π/3)r²h

where r is the radius of the base and h is the height. We want to find the diameter of the base, so we can rewrite this in terms of diameter and solve for d. Please note that the height is given in millimeters, not inches, so a conversion is necessary.

  V = (π/3)(d/2)²h

  12V/(πh) = d²

  d = 2√(3V/(πh)) = 2√(3(2.2×10^4 in^3)/(π·1530 mm/(25.4 mm/in))

  = 2√(1.6764×10^6/(π·1.53×10^3) in^2)

  d ≈ 37.35 in

The base diameter of the cone is about 37.35 inches.

What is the approximate length of the radius of a circle with a circumference of 63 inches?
Sergeeva-Olga [200]

Answer: 63/2π

Step-by-step explanation: C=πd  

                                             63=πd

                                             D=63/π

r=1/2d

1/2×63/π=<u>63/2π</u>

On Monday, a local hamburger shop sold a combined total of 556 hamburgers and cheeseburgers. The number of cheeseburgers sold wa
Klio2033 [76]
H = number of hamburgers sold.
c = number of cheeseburgers sold.

we know that "c" is three times the number of "h", thus c = 3h

we also know, the total amount sold for both is 556,  h + c = 556

h + c = 556
c = 3h
thus

h + (3h) = 556 <---- solve for "h" to see how many hamburgers were sold.

what about "c"? well, c = 3h
