DIA [1.3K]

Answer:

  π(3 in)²(10 in) -8(4/3)(1.5 in)³

Step-by-step explanation:

The volume of a cylinder with a radius of 3 inches and a height of 10 inches is ...

  V = πr²h = π(3 in)²(10 in)

The volume of 8 spheres with a radius of 1.5 inches is ...

  V = 8(4/3)πr³ = 8(4/3)π(1.5 in)³

The volume occupied by the water is the volume of the cylinder not occupied by the spheres. So, it is ...

  V = π(3 in)²(10 in) -8(4/3)(1.5 in)³ . . . . . . matches the 4th choice

pickupchik [31]

Answer:

Object will be at a distance of 358098.6 km from the source

Step-by-step explanation:

We have given angle = 0.0008 degree =\frac{0.0008\times \pi }{180}=4.444\times 10^{-6}\pi

Radius is given = 2.50 km

Linear size of the object will be equal to diameter

So linear size = 2.5×2 = 5 km

We know that linear size =distance \times \Theta

So 5=d\times 4.444\times 10^{-6}\pi

d = 358098.6 km

Hello :)

We know that an answer in square feet would require us to calculate the area. In order to calculate the area of a rectangle, we multiply the length times the width. So, we have 6 x 2 which is 12 Therefore, the area is 12 square feet.

6[]

2

6+6+2+2=16

Have a nice day :)
