-8,-3 if i read that correctly, that should be the answer.
Answer:
The height is 15 feet
Step-by-step explanation:
If you use the formula for cone height and substitute in your values:
h=3 x (V/πr^2)
h=3 x (81430.1/72^2π)
h=15
1/16 You need to multiply 2x2x2x2 since all the coins are both two sided
45 square feet is the area of the base of the pedestal.
what is rectangular prism?
- A rectangular prism is a 3D figure with 6 rectangular faces.
- To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
we know that
The volume of the pedestal (rectangular prism) is given by the formula
V = B × h
where
B is the area of the rectangular base of pedestal
V = 405 ft³
h = 9 ft
put the given values in the formula and solve for B
405 = B × 9
B = 405/9
B = 45 ft²
Therefore, 45 square feet is the area of the base of the pedestal.
