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.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
