Rina8888 [55]

Answer:

  • 31.8 cm

Step-by-step explanation:

<u>Volume of a cone:</u>

  • V = 1/3πr²h

<u>We have:</u>

  • V = 1200 cm³
  • r = 6 cm
  • h = ?

<u>Substitute values and solve for h:</u>

  • 1200 = 1/3*3.14*6²h
  • 1200 = 37.68h
  • h = 1200/37.68

Find, to the nearest tenth, the area of the region that is inside the square and outside the circle. the diameter of the circle
Doss [256]

Answer:

Option 42.1\ in^{2}

Step-by-step explanation:

we know that

The area of the region that is inside the square and outside the circle is equal to the area of the square minus the area of the circle

see the attached figure to better understand the problem

Step 1

<u>Find the area of the square</u>

Remember that

The area of the square is

A=b^{2}

where

b is the length side of the square

we have

b=14\ in

substitute

A=14^{2}=196\ in^{2}

Step 2

<u>Find the area of the circle</u>

Remember that

The area of the circle is equal to

A=\pi r^{2}

we have

r=14/2=7\ in

substitute

A=\pi(7^{2})=153.9\ in^{2}

Step 3

<u>Find the area of the region</u>

196\ in^{2}-153.9\ in^{2}=42.1\ in^{2}
