Two similar cones have volume of 343pi cubic centimeters and 512pi cubic centimeters. The height of each cone is equal to 3 times its radius. Find the radius and height of both cones

For the first cone: r = 7 cm, h = 21 cm

For the second cone: r = 8 cm, h = 24 cm

Step-by-step explanation:

The volume of the first cone is

The volume of the second cone is

We are told that the height of each cone is 3 times its radius, hence:

h = 3r

The volume of a cone is given as:

Substituting h = 3r:

For the first cone, V = , radius, r, will be:

∴ Its height will be:

h = 3r = 3 * 7 = 21 cm

For the second cone, V = , radius, r, will be:

∴ Its height will be:

h = 3r = 3 * 8 = 24 cm

The radius and height of the first cone are 7 cm and 21 cm respectively while the radius and height of the second cone are 8 cm and 24 cm respectively.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
