What is the volume of the cone? use π ≈ 3.14.

a. 12.56 cubic units
b. 18.84 cubic units
c. 20.93 cubic units
d. 25.12 cubic units

Option (a) is correct.

The volume of cone is 12.56 cubic meters.

Step-by-step explanation:

Given : A oblique cone with slant height = 5 units and diameter = 4 units.

We have to find the Volume of the given oblique cone.

Consider the given oblique cone with slant height = 5 units and diameter = 4 units.          

In a right angle triangle, the square of hypotenuse is equal to the sum of  square of base and perpendicular.

that is  

Apply Pythagoras theorem,

We have,

h = 5 and b = 4

Thus,

Solve for p , we have,

Thus, p = 3 (as length cannot be negative)

Thus, the height of cone is 3 units

Volume of cone =

Put r = 2 and h = 3 and π ≈ 3.14.

We have,

Volume of cone =

Simplify, we have,

Volume of cone = 12.56 units³

Thus, The volume of cone is 12.56 cubic meters.

i belive those are the ones that are under 90 degreese.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
