Find the volume of the cone.

Mathematics

Answer:

96π

301.59

Step-by-step explanation:

The volume of a cone can be calculated using the following formula:

V=\frac{1}{3}bh

b is the base and h is the height. The base formula for a circle (area):

b=\pi r^2

Insert this value into the formula:

V=\frac{1}{3}\pi  r^2h

Simplify the formula:

V=\frac{\pi r^2h }{3}

Now insert the known values:

V=\frac{\pi(6)^2(8) }{3}

Simplify:

V=\frac{\pi*36*8 }{3}\\\\V=\frac{288\pi }{3}\\\\V=96\pi

The volume is 96π units³ or 301.59 units³.

The lengths of the legs of a 45°-45°-90° triangle can be described by the expressions 4x – 12 and x + 6. What is the length of t
Anastasy [175]

Answer:

12

Step-by-step explanation:

Legs of 45-45-90 are equal so 4x-12=x+6.

3x=18, x=6

Plug back in and the length is 12

How do you do these? Do you add or multiply the exponents?
Monica [59]
Hey with that question you multiply the number in the Parentheses with the exponent, once you do that to each number multiply the two numbers together.

What is the measure of angle c?​
s344n2d4d5 [400]

Answer:

50 degrees

Step-by-step explanation:

Okay! So first off, because this is NOT a right triangle, we can't use soh cah toa. That means we can either use the law of sines or the law of cosines.

Because we only have sides here and no angles, we are forced to use the law of cosines.

c^2 = a^2 + b^2 − 2ab cos(C)

c = 6

b = 7.5

a = 6.5

36 = 6.5^2 + 7.5^2 - 2(6.5)(7.5)cos(C)

36 = 98.5 - 97.5cos(C)

-62.5 = -97.5cos(C)

0.641 = cos(C)

angle C = cos^-1(0.641)

angle C = 50.13 which is around 50 degrees

Remember! A dumb thing i always used to do in geometry was use radians instead of degrees, be sure to use degrees here because you are looking for degrees. Radians are for things involving not degrees, but PI.
