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

Don't feel bad, this is an odd question and the parenthesis do not seem to be required. Following the order of operations would result in the same answer anyway...

Odd.

Solve the linear equation. 8x+32=2(25x−15)−11x8x+32=2(25x−15)−11x
Bogdan [553]
It seems like you put the same equation up there twice, but no worries! :)

8x + 32 = 2(25x - 15) - 11x

Simplify.

8x + 32 = 50x - 30 - 11x

Add like terms.

8x + 32 = (50x - 11x) - 30

Simplify.

8x + 32 = 39x - 30

Now we must subtract 32 from both sides.

8x = 39x - 30 - 32

Then, subtract 39x from both sides.

8x - 39x = -30 - 32

Simplify.

-31x = -62

Finally, divide both sides by -31.

-31x ÷ -31 = -62 ÷ -31

Simplify.

x = 2

~Hope I helped!~
