WILL REWARD BRAINIEST! What is the volume of the composite figure if both the height and the diameter of the cylinder are 10.5 f
Mashutka [201]

Answer:

908.74

Step-by-step explanation:

The formula for the volume of a cylinder is V = h * pi * r^2

h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.

So now plug it into the formula:

V = 10.5 * pi * (5.25)^2

= 908.74

Hope this helped! :)

If a room is 20 by 24 feet, how big is it on a floor plan where 1/2 inch represents 1 foot?
Naddik [55]
Well if you take the room being 20 x 24. Thats 480 feet. But you want how large in 1/2 inch. 1/2 inch is 1/24 of a foot. So if we take 480 feet being 1 and times it by 24. (480 x 24) You get 11,520 half inches. Brainliest would be much appreciated if you feel its deserved.

lord [1]

Answer:

mean =  \frac{9 + 4 + 4 + 1 + 0 + 6 + 4}{7}  =  \frac{28}{7}  = 4

mean \: deviation =  \frac{ |9 - 4| +  |4 - 4|  +  |4 - 4|   +  |1 - 4| +  |0 - 4| +  |6 - 4|   + |4 - 4| }{7}  =  \frac{5  + 0 + 0 + 3 + 4 + 2 + 0}{7}  =  \frac{14}{2}  = 7
