Answer:
Area of sector = 144.4π cm²
Step-by-step explanation:
Given:
Perimeter of circle = 40π cm
Given angle = 130°
Find:
Area of sector
Computation:
Perimeter of circle = 2πr
⇒ 40π = 2πr
⇒ 40 = 2r
⇒ Radius r = 40 / 2
Radius r = 20 cm
Area of sector = [θ/360][π][r]²
⇒ Area of sector = [130/360][π][20]²
⇒ Area of sector = [0.361][π][400]
Area of sector = 144.4π cm²

Step-by-step explanation:
<u>Here :-</u>
- Selling price of 25 balls is equal to the Cost of 15 balls
<u>Let the cost price of one ball is ₹1. So ;-</u>
- Cost price of 25 balls = ₹25
- Cost price of 15 balls = ₹15
↝ Here the selling price of 25 balls is equal to the cost of 15 balls. It means C.P of 15 balls = S.P of 25 balls. So, the selling price of 25 balls is ₹15.
<u>Firstly, finding the loss :-</u>
<em><u>∴ The loss is Rs.10.</u></em>
<u>Now, finding the loss percentage :-</u>
<em><u>∴ The loss percent is 40%.</u></em>
