Answer:
Arc length = radius * central angle * PI/180
Arc length = 5 * 180 * PI/180
Arc length = 5 * PI
Arc length = 15.7079632679
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
To solve for x, you have to multiply the terms in parenthesis by 3. Then you add 6 to each side of the equal sign. Then you divide each side of the equal sign by 3 to get x=7
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
6.21 --subtract 1.05 from 7.26
