S=2pirh for h i need help please

Answer:

Length of arc of a circle is given by:

    .....[1]

where

L is the length of an arc

r is the radius of  the circle.

As per the statement:

Diameter of the circle(D) = 6 inches.

we know that:

D  =2r

6 = 2r

Divide both sides by 2 we get;

3 = r

or

r = 3 inches

We have to find the long arc arc subtended by an angle measuring 70°.

Substitute the value of r = 3 inches and in [1] we have;

Simplify:

L = 210 inches

Therefore, 210 inches long is the arc subtended by an angle measuring 70 degree.

Answer:

D is the right answer.

Answer: 25

Step-by-step explanation:

because its funnier than 24.

If you square an integer, there is no way to get a negative as a result.

Let's look at -5².

-5² means -5 × -5 or 25.

6² means 6 × 6 or 36.

So, there is no way to end up with a negative.

Answer:

7 squared is 49 4 squared is 16.. So it's 49 Pi minus 16 pi. And that's going to be 33 pi.

So the answer is 33 pi.
