Answer:

  100π square inches

Step-by-step explanation:

The area of a circle is given by ...

  A = πr^2

where r is the radius. The radius of a circle is half the diameter, so your circle with 20 inch diameter has a radius of 10 inches. Putting that value into the formula gives an area of ...

  A = π·(10 in)^2 = 100π in^2

The area is 100π square inches.

The area of a rectangle is 30 square root 3750 square inches, and the length is 3 square root 250 inches what is the width of th
Ann [662]

Answer:

width=10\sqrt{15}\ in

Step-by-step explanation:

-A rectangle's area is given by:

A=lw\\\\l=length\\w=width

Given A=30\sqrt{3750} and l=3\sqrt{250}, we substitute in the formula to solve for the width as follows:

A=lw\\\\30\sqrt{3750}=3\sqrt{250}\times w\\\\w=\frac{30\sqrt{3750}}{3\sqrt{250}}\\\\w=10\frac{\sqrt{3750}}{\sqrt{250}}\\\\=10\times \sqrt{\frac{3750}{250}}\\\\=10\sqrt{15}\ in

Hence , the rectangle's width is 10\sqrt{15}\ in

What is the value of x?
Talja [164]
Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

a^{2} + b^{2} = c^{2}

Plug in the known values into the equation:

a = 6, c = 10

6^{2} + b^{2} = 10^{2}

36 + b^{2} = 100

Subtract both sides by 36.

b^{2} = 64

Square root both sides to get b by itself.

\sqrt{64} = 8

b = 8

The value of x is 8.

If you drew a horizontal line on the coordinate plane, what could you say about the y-coordinate for every point on the line?
sattari [20]
It's the y intercept.
If y = a then every point on the line would be (x,a)
The lines slope is 0.  I know that has nothing to do with the question, but it is true and it gives me 3 things to tell you.

Someone could help me with problem 3-76 (b) pls
kupik [55]

Answer:

ok so you see the equation at the top... you are going to "plug in" the number in the "in" row to get the "out number

Step-by-step explanation:

example

in: 4

-2(-4)+1

8+1

9

so for the out row under -4 you would put 9

-2(-3)+1

6+1

7

so for the out row under 3 you would put 7
