If Both carpenters working together hours or 2.1 hours will take to build one shed.
Step-by-step explanation:
The given is,
First carpenter estimates that it will take him 3 hours to build a shed
Other carpenter estimates it will take him 7 hours to build a shed
Step:1
Formula to find 1 hour work of carpenters (Ref. Dr. R.S. Aggarwal book)
One hour's work =
Where, n - Number of working hours
From the given,
First carpenters one hour work =
Other carpenters one hour work =
If both are working together,

= hours = hours
Result:
If Both carpenters working together hours or 2.1 hours will take to build one shed.
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>
