Step-by-step explanation:

(1) The radius of sphere is 4.5 units.

The volume of volume of sphere is given by :

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

\pi=3.14\ , r=4.5

So,

V=\dfrac{4}{3}\times 3.14\times (4.5)^3

Option C is correct.

(2) If we solve the plugged values, then we get :

V=\dfrac{4}{3}\times 3.14\times (4.5)^3

V=381.5\ \text{units}^3

Option C is correct.

First answer gets brainalist On a scale model of a building, 14 inch represents 38 foot. What length on the model represents 1 f
miskamm [114]

Answer:

7/19 in.

Step-by-step explanation:

Use a proportion. Let x equal the unknown model length.

model/real = (14 in.)/(38 ft) = x/(1 ft)

(14 in.)/(38 ft) = x/(1 ft)

Cross multiply.

38 ft * x = 1 ft * 14 in.

Divide both sides by ft.

38x = 14 in.

Divide both sides by 38.

x = (14 in.)/(38)

x = 7/19 in.

Can someone help me please
natali 33 [55]

Answer:

The answer to number one is 11√17

The answer to number two is 4

Step-by-step explanation:

In number one: once you get both radicands to be equal, then you can add them. Like of it like 3x+2x. The x’s are like terms, so you can add them together.

In number two: the √5 on the top and bottom cancel out. This leaves 12/3 which is equal to 4.
