A cone and a cylinder have the same height and their bases are congruent circles

sveticcg [70]

Answer:

30 cm^3

Step-by-step explanation:

Given

radius for both shape = r

height for both shape = h

volume of cylinder is given by $\pi r^2h$

volume of cone is given by $1/3(\pi r^2h)$

From above two equation we can see that $\pi r^2h$ is volume of cylinder

thus we can say that volume of cone is 1/3(volume of cylinder)

So we can say that for any cylinder and cone whose height is same and base is congruent

volume of cone will be one-third of volume of cylinder.

Now in given problem

volume of cylinder is 90 cm^3

So , volume of given cone will be one-third of 90 cm^3

which is 1/3*90 cm^3 = 30 cm^3.

Thus, volume of the given cone is 30 cm^3.

Can someone PLEASE answer this question (picture above)

Vedmedyk [2.9K]

Answer:

11.89

Step-by-step explanation:

let x be the increases length

now (6.4+x)(4+x)(10.5+x) = 2*250

solving this we get x = 1.39

so the largest dimension is 10.5+ 1.39 = 11.89

To find the height of a pole, a surveyor moves 150 feet away from the base of the pole and then, with a transit 4 feet tall, mea

ladessa [460]

Answer: The answer is 139 feet

H = height of the pole =?

BC = ED = height of the transit = 4 ft

CD = BE = distance moved away from the base of the pole = 140 ft

Consider the ΔABE

tan44 = AE/BE

tan44 = h/140

h = 140 tan44

h = 135.2 ft

H = height of pole = AE + ED = h + ED = 135.2 + 4

H = 139.2 ft
