Answer:

V = 564.15 ft^3

Step-by-step explanation:

The formula for the volume of a cone of base radius r and height h is

V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is

V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

Helen [10]

Hey, Melany. To answer this problem, simply set up a proportion: $\frac{18.75}{100} = \frac{x}{128}$ . Now let's solve for x.

- Cross multiply: $\frac{18.75*128}{100*x} --> 2400 = 100x$

- Isolate x:

$\frac{2400}{100} = \frac{100x}{100}$

This means that x = 24.

There are 24 9th graders in the band.

Write the equation of the line that passes through the points (-2,-1)(−2,−1) and (2,4)(2,4). Put your answer in fully reduced po

snow_tiger [21]

Answer: y= 5/4 + 3/2

Step-by-step explanation: Your equation is y=mx +b. You have to subtract the second y from the first y, and the second x from the first x to find the slope. This equation would be 4-(-1) over 2-(-2). So your slope will be 5/4. Now to find the y-intercept you can choose either (x,y) point. For example if you are using (2,4) you would do b= 4-(5/4)(2). b=3/2.

BRAINLIESSTTTT!!!

Yuri [45]

The answer would be B because the sum of the squares of the 2 shorter sides equal the square of the longer side, which is the pythagoream theorem of a^2+b^2=c^2.

The volume in cubic centimeters of a sphere whose diameter is 6 centimes is ?

aivan3 [116]

Answer:

Volume of the sphere is 36π (or) 113.097 cubic centimetre.

Step-by-step explanation:

$given \\ diameter \: of \: sphere = 6 \: cm \\ radius \: of \: sphere \: = \frac{diameter}{2} \\ radius \: = \frac{6}{2} \\ radius \: (r) = \: 3 \: cm \\ volume \: of \: sphere \: = \frac{4}{3} \pi \: {r}^{3} \\ here \: r \: = 3 \: cm \\ on \: substituting \: r \: = 3 \: \: in \: formula \\ volume \: of \: sphere \: = \frac{4}{3} \pi \: {3}^{3} \\ \: \: = \frac{4}{3} \pi \: 27 \\ \: = \: 4 \pi \times 9 \\ \: \: = 36\pi \\ \: \: = 113.097 \: {cm}^{3}$
