We know that
l² = r² + h²
l² = (10.5)² + (36)²
l² = 110.25 + 1296
l² = 1406.5
l = √(1406.5)
l = 37.5 cm
Now,
CSA of cone = πrl
=> 22/7 × 10.5 × 37.5
=> 22 × 1.5 × 37.5
=> 1237.5 cm²
Area of 20 caps = 20 × 1237.5
=> 24750 cm²
2x-y=4
Therefore: y=2x-4
---------------------------------
5x-10/4(2x-4)=10
5x-5/2(2x-4)=10
5x-5x+10=10
10=10

Answer:
A = π(34), or approx. 106.8 units²
Step-by-step explanation:
Recall that the formula for the area of a circle is A = πr².
If (3, 5) is a point on the circle at hand, then the radius (found using the Pythagorean Theorem) is r = √(3² + 5²) = √(9 + 25) = √34.
Then r² = 34, and the area of this circle is
A = π(34), or approx. 106.8 units²
