A cone has a slant length of 10 and a diameter of 8. Height is unknown.

patriot [66]

Answer: 153.56

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Volume of a cone: 1/3 π r² h

Where r is the radius and h is the height (unknown)

Diameter = r x 2

8 = 2r

8/2 =r

r = 4

Before calculating the volume we have to apply the Pythagorean Theorem to find h. (where the slant is the hypotenuse and h and r are the sides of the triangle)

10 ² = h² + 4²

Solving for h

100 = h² + 16

100-16 = h²

84= h²

√84 =h

9.16= h

Back on the volume formula:

V= 1/3 π r² h

V =1/3 π 4² (9.16) =153.56

Answer:

$\Huge\boxed{z$

Step-by-step explanation:

Hello There!

Once again we need to isolate the variable using inverse operations

to get rid of the -8.2 we add 8.2 to each side

-8.2+8.2 cancels out

-9.7+8.2=-1.5

now we have

-1.2z>-1.5

now we wan to get rid of the -1.2

to do so we want to divide each side by -1.2

$\frac{-1.2z}{-1.2} =z\\\\\frac{-1.5}{-1.2} =1.25$

Remember we have to flip the inequality sign because we're dividing by a negative number

we're left with

z<1.25
