Water is being poured into a container in the shape of a right circular cone with a radius of 4 ft and height of 16 ft. find a function that models the volume v of the water in the cone in terms of the height (h) of the water.

Step-by-step explanation:

Volume of a right circular cone can be found using the equation

where

Since r=4ft, we can model the volume of the water in the cone in terms of the height as

=

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.
