Answer:
Arav is 30 and Pawan is 40
Step-by-step explanation:
We can call Arav's age x and Pawan's age x + 10, therefore we can write the following equation:
1/7((x + 10) - 5) = 1/5(x - 5)
1/7(x + 5) = 1/5(x - 5)
5(x + 5) = 7(x - 5)
5x + 25 = 7x - 35
-2x = -60
x = 30 so x + 10 = 40
Cone Volume = (PI * radius ^2 * height) / 3
Cone Volume = (PI * 2^2 * 5) /3
Cone Volume = (PI * 20) / 3 <span>
