Answer:

100π

Step-by-step explanation:

The formula for calculating area of a circle π×r^2 (r: radius)

The given radius here is 20 ÷ 2 = 10

π × 10^2 = 100π

Answer:

Step-by-step explanation:

Since area of a circle is pi.r^2

We know that diameter is 20

Radius is half of diameter

So it becomes

Pi.(d/2)^2

So pi.(40/4) is the area of this circle.

Or 40pi/4

Another way of finding Surface Area is

  1. SA= 2LW+2LH+2HW

L= Length

W= Width

H= Height

the answer, and explained, would be this

2. SA= 2(12)(10)+2(12)(16)+2 (10)(16)

(<em>multiply</em>)

3. SA= 240 + 384 + 320

(<em>add</em>)

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em>.</em><em>.</em><em> </em>

<em><u>SA</u></em><em><u>=</u></em><em><u>944ft3</u></em><em><u> </u></em>

Solve for 6y+12=3y-3
kherson [118]
6y + 12 = 3y - 3

Subtract 3y on both sides

3y + 12 = -3

Subtract 12 on both sides

3y = -15

Divide by 3 on both sides

y = -5

A) Your primary concerns are the points B and E, so y> .5x+4 and y>or= x-4B) choose one or both points, and enter them into the equations. If the statements are true, then the equations work
 for problem C So, any point in the shaded area, but not on the line, are valid points for Natalie's school
