5 0

Answer:

Step-by-step explanation:

x = the number

x + 1/6x + 2 1/2x + 7 = 12 1/2

3 + (1/6 + 1/2)x = 12 1/2 - 7

3 + (1/6 + 3/6)x = 5 1/2

3 2/3x = 5 1/2

x = (11/2) / (11/3)

x = 11 / 2 * 3 / 11

x = 3/2

x = 1 1/2

What is the volume of a right circular cone that has a height of 14.9 cm and a base with the circumference of 2.9 cm rounded to

xxMikexx [17]

Answer:

The answer to your question is Volume = 3.30 cm³

Step-by-step explanation:

Data

Volume = ?

height = 14.9 cm

circumference = 2.9 cm

Process

1.- Calculate the radius

circumference = 2πr

-Substitution

2.9 = 2πr

-Solve for r

r = 2.9/2π

r = 1.45/π cm

2) Calculate the volume of the cone

Volume = 1/3πr²h

-Substitution

Volume = 1/3π(1.45/π)²(14.9)

-Simplify

Volume = (1.04)(0.213)(14.9)

Volume = 3.30 cm³
