Hello!

We first have to find the volume of the bigger cylinder

We use the equation \pi  r^{2} h

Put in the values you know

\pi 10.5^{2} *18

This is 6234.49

Now we find the volume of the cut out part

\pi  7.5^{2} 18

This is 3180.86

We subtract the two values

6234.49 - 3180.86 = 3053.63

The answer is 3053.6

Hope this helps!

How do you get 25 for the order of operations

PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.

A leg of a right triangle can never be greater then the hypotenuse

this formula will tell you if it's a valid right triangle
{?}^{2} + {?}^{2} = {?}^{2}
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.

THE STEPS:
{3}^{2} + { \sqrt{7}^{2} } = {4}^{2}
9 + {2.65}^{2} = 16
{2.65}^{2} = 7
9 + 7 = 16
ANSWER: \sqrt{7}

Ok so I found the area of a rectangle.
Kay [80]

Answer:

  circle area = 1963.495 ft²

Step-by-step explanation:

<u>Given</u>

  A rectangle 550 ft by 350 ft packed with circles on a rectangular grid

<u>Find</u>

  the area of the largest circle that can be packed this way

<u>Solution</u>

The diameter of the circle must be a factor of both 350 and 550. We want the diameter to be the largest such factor. We can write the factors of 350 and 550 as ...

  • 350 = 50 × 7
  • 550 = 50 × 11

The largest factor common to both numbers is 50, so that will be the diameter of the largest circle that will fit on a square grid.

The area of a circle is commonly given by the formula ...

  A = πr² . . . . . where r represents the radius of the circle.

The radius is half the diameter, so will be (50 ft)/2 = 25 ft. And the area of the circle is ...

  A = π(25 ft)² = 625π ft² ≈ 1963.495 ft²

The area of one circle is about 1963.495 square feet.

_____

The total number of circles is 11×7 = 77. Their total area is 77×1963.495 ft² ≈ 151,189 ft². This is 151,189/192,400 ≈ 78.54% of the total area of the rectangle.
