Answer:
615.44 mm²
Step-by-step explanation:
Before finding the area of the circle, first, let us find the radius of the circle.
Given that,
diameter ⇒ 28 mm
Therefore,
<h3>d = 2r</h3>
28 = 2r
Divide both sides by 2.
14mm = radius
<u> </u>
And now, let us find the area.
The formula to find the area of the circle is :
<h3>Area = π r²</h3>
Let us solve now.
Area = π r²
= 3.14 × 14 × 14
= 43.96 × 14
=<u> 615.44 mm²</u>
Answer:
that's alot but no english speak english it is long
A pair of numbers is a solution of y = -3x if the second number, y, is -3 times the first number, x.
What about the pair (-1, 4)? If you replace x with -1, you get y = -3(-1) = 3, not 4. So (-1, 4) is NOT a solution.
For each answer choice, you have to check all three of the given pairs.
(0, 0) is a solution because if x = 0, then y = -3(0) = 0.
(3, -9) is a solution because if x = 3, then y = 3(-3) = -9.

Answer:
m = 13
Step-by-step explanation:
To isolate the variable, you undo what is being done to it. Here, we have the variable being multiplied by 7, hence, we divide both sides by 7 and the result is the variable isolated and solved.
1. 7m = 91
2. (7m)/7 = 91/7
3. m = 13
