The height of the pyramid in the diagram is three times the radius of the cone. The base area of the pyramid is the same as the base area of the cone. What is the expression for the volume of the pyramid in terms of the radius r of the cone?

Answers

Answer 1

Answer: B(cone)=B(pyramid)=r²π
V(pyramid)=1/3 * B * H = 1/3 * r² π * 3 r ( 3 will cancel out )= r³ π
Answer: r³ π

Answer 2

Answer: Hello,

base of the pyramid :πr²
height=r

Volume=b*h/3=1/3* π*r^3

Renata moved to her new home a few years ago. Back then, the young oak tree in her back yard was 1 9 0 centimeters tall. She measured it once a year and found that it grew at a constant rate. 3 years after she moved into the house, the tree was 2 7 4 centimeters tall.

Answers

It would grow 28 centimeters each year. 274-190=84 which is the difference from 3 years. You would then divide the 84 between three different years to get 28.

Miranda wants to give her 14-year-old daughter $20,000 when she turns 18. How much does she need to put in the bank now if the interest rate is 10 percent per year?
