(1/2) π r² h = (1/2) * (3.14) * (30)² * 100 = ?
(30)² * 100 = 30 * 30 * 100 = 90,000.
So, we have: (1/2) * (3.14) * (90,000) ;
→ (1/2) * (90,000) = 45,000 ;
So, we have: (3.14) * (45,000) = 141,300 units.

Is that a question or a true or false question..
Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years
