Answer:
Keep the ladder at a 66 degree angle of elevation at most.
Step-by-step explanation:
Hypotenuse is 20 feet
Adjacent side is 8 feet
We use inverse cosine to find the angle
arccos(8/20) = 66.4 deg

(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.
