Answer:

113.1

Step-by-step explanation:

Volume of sphere = \frac{4}{3} × π × r²

Volume of sphere =  \frac{4}{3} × π × 3²

Volume of sphere =  \frac{4}{3} × π × 9

Volume of sphere =  \frac{4}{3} × 9 π

Volume of sphere = 113.1

Answer:

V=113.1cm^3

Step-by-step explanation:

The formula to calculate the volume of a sphere is:

V=\frac{4}{3}\pi r^3

Where r is the radius of the sphere.

In this case we do not know the radius of the sphere, but we know the diameter.

By definition the diameter of a sphere is equal to twice the radius. This is:

d = 2r

r = \frac{d}{2}

In this case d=6 cm

So

r = \frac{6}{2}

r = 3\ cm

Finally

V=\frac{4}{3}\pi 3^3

V=36\pi\ cm^3

V=113.1cm^3

Kathleen correctly determines four arithmetic means between −7 and 14. What values does Kathleen determine?
Annette [7]

Answer:

  Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.

Step-by-step explanation:

The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...

  21/5 = 4.2

The four means are ...

  -7 +4.2 = -2.8

  -2.8 +4.2 = 1.4

  1.4 +4.2 = 5.6

  5.6 +4.2 = 9.8

The Student Council is making six right triangular pennants to promote school spirit. Each right triangle is 9 inches high and 2
pentagon [3]
I'm kinda guessing but I think it's 4.5 square feet because each triangle has 108 inches of area when you multiply by 6 you get 648 then from there you turn that into square feet

dlinn [17]

Answer: 60 yd

Step-by-step explanation:

Here: subdivided into 3 smaller pens (2w + w + w) extra widths for separation purposes (3 smaller pens)

180 yards of fencing material

180yd = 2L + 4w

180dy = 2*60 + 4w

60dy = 4w

w = 15yd, how wide can the rectangle can  be with L = 60yd
