The diameter of a circle is 10 millimeters. The circumference of the circle is 62.8 millimeters.

Vilka [71]

Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.

DOUBLE PTS please help me ill give brainilist

-Dominant- [34]

This problem should not give you too much difficulty. The area of a triangle is (LxH)/2. The area of a rectangle is LxH. Calculate the area of each triangle and the three rectangles.

When added together, you should get 75.75cm².

I would show the work for you, but just work through it slowly, and you should get the same thing.

X/9+3<4 what is the solution to the ineqaulity

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the solution to the inequality:

$\star~\large\pmb{\cfrac{x}{9}+3 < 4}$

$\triangle~\fbox{\bf{KEY:}}$

First, subtract 3 from both sides, then multiply both sides by the denominator.

Step 1.

$\star~\large\pmb{\cfrac{x}{9} < 4-3}$

$\star~\large\pmb{\cfrac{x}{9} < 1}$

Step 2.

$\star~\large\pmb{\cfrac{x}{9}\times9 < 1\times9}$

Notice that on the left, the 9s cancel, and we're left with x.

Step 3.

$\star~\large\pmb{x < 9}$

This is the solution.

Hope it helps you out! :D
