Answer:
18.852
Step-by-step explanation:
Formula to find the arc of semi circle is :
Arc length = π r
Given that,
diameter ⇒ 12
So, the radius will be,
Radius ⇒ 12 / 2
⇒ 6
<u>Let us solve now.</u>
Arc length = π r
= 3.142 × 6
=<u> 18. 852</u>
I’m so confused. Is there any other part to the question?
Answer:
<h2><u><em>
5 and 7</em></u></h2>
Step-by-step explanation:
One number is 2 more than another. The difference between their squares is 24. What are the numbers?
(x + 2)² - x² = 24
x² + 4x + 4 - x² = 24
4x + 4 = 24
4x = 20
x = 20 : 4
x = 5
----------------------
5 + 2 = 7
check
(5 + 2)² - 5² = 24
49 - 25 = 24
24 = 24
the answer is good
