Volume of Solids
The volume of the solid is 758.83 in³
Step-by-step explanation:
Given that the cone and half sphere is hollow
The volume of the cone =
The Volume of the sphere =
So the Volume of the half sphere =
The volume of solid = volume of cone + volume of the half sphere
Given
height h = 19 in
radius r = 5 in
=
= 1/3 × 3.14 × 5 × 5 × 19
= 497.16 in³
= 2/3 × 3.14 × 5 × 5 × 5
= 261.67 in³
V = 497.16 in³ + 261.67 in³
= 758.83 in³
Hence the volume of the solid is 758.83 in³
Answer:
The amount in 20 years is $6,050.24
Step-by-step explanation:
Given the following information:
Principal (Present Value, or PV)= $3,100
Interest rate ( <em>r </em>)= 3.4% or 0.034
Number of compounding period (<em>n </em>)= 1 (annually)
Number of years ( <em>t </em>)= 20
We can use the Future Value formula to find out the value of $3,100 in 20 years:
FV = 3100(1.95169)
FV = $6,050.24
Therefore, the future value of the amount deposited is $6,050.24
