Answer:

21.7

Step-by-step explanation:

First, find the area of the rectangle.

A = lw

The width is 8 and the length is 9.

A = 8(9)

A = 72 units squared

Next, two semicircles would make one entire circle. There are 2 semicircles. So, you would subtract the area of the circle from the area of the triangle.

A=pi(r^2)

The diameter is 8, so the radius is 4.

A = pi(4^2)

A = pi(16) or 16pi

72 - 16pi = 21.7 units squared

Answer:

There are 25920 cubic inches and 0.56 cubic yards in the box.

Step-by-step explanation:

Given:

The dimensions of the box are 3 in by 2 ft by 10 yd.

Convert all in inches.

We know that, 1 ft = 12 in

So, $2\textrm{ ft} = 2\times 12 = 24\textrm{ in}$

Also, 1 yd = 36 in

So, $10\textrm{ yd} = 10\times 36 = 360\textrm{ yd}$

Now, volume of the box in cubic inches is given as:

$V=3\times 24\times 360=25920\textrm{ }in^{3}$

Now, we know that,

$1\textrm{ in} = \frac{1}{36}\textrm{ yd}\\1\textrm{ }in^{3}=\frac{1}{36^{3}}\textrm{ }yd^{3}$

Therefore,

$25920\textrm{ }in^{3}=25920\times \frac{1}{36^{3}}= 0.56\textrm{ }yd^{3}$

So, there are 25920 cubic inches and 0.56 cubic yards in the box.

What’s the answer to 8-10?

vovangra [49]

Answer:

-2

Step-by-step explanation:

When you have equations with smaller number subtracting bigger numbers, it means that you are always going to end up with a negative answer. So if you do 10-8 it would just be 2, but if you flip it , it will be a negative so the the answer would be

8-10= -2

Hope that helped or it probaly just made you more confused lol
