A cylinder-shaped cup and a cone-shaped cup both have radii of 3 inches and heights of 5 inches. Compare the volumes of the two cups.

The cylinder-shaped cup has a volume of 141.3 inches cubed. The cone-shaped cup has a volume of 47.1 inches cubed.

Step-by-step explanation:

The formula to find the volume of a cylinder is πr²h.

Since we know that the radius is 3 inches and the height is 5 inches, we can plug the numbers into the equation.

π(3²)(5) = 141.3

(Make sure to use 3.14 as pi)

The formula to find the volume of a cone is 1/3πr²h.

Since we know that the radius is 3 inches and the height is 5 inches, we can plug the numbers into the equation.

1/3π(3²)(5)= 47.1

The volume of the cylinder is 141.3 inches³ while the volume of the cone is 47.1 inches³.

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
