Determine the height of a cone that has a diameter of 10 inches and a volume of 225 in^3

h= 21.4859173174 in (about)

Step-by-step explanation:

This is a formula to determine the height of a cone: Given radius and volume calculate the height, slant height, lateral surface area and total surface area.

Given r, V find height

h = (3 * v) / (πr2)

h=3x225/π5(10/2=5, to find the radius)x2

h=675/π10

h=675/31.4159265359 (about)

therefore, h= 21.4859173174 in (about)

answer: 40.95

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
