Amedium sized paper cone has a diameter of 8 cm and a height of 10 cm what is the volume of the cone

V =167.5516082 cm^3

Step-by-step explanation:

Volume of a cone is given by

V = 1/3 pi r^2 h

We have the diameter, so we need to get the radius

d= 2r

Divide by 2

d/2 =r

8/2 =r

4= r

V = 1/3 *pi *(4)^2 *10

   = 1/3 *pi*16*10

        53 1/3 pi  cm^3

Let pi = 3.14

V =167.5516082 cm^3

expression #3 is not equivalent. the others are.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
