Answer:
1) volume = 102.92 m²
2a) Perimeter = 28 inches
2b) Actual perimeter = 672 inches or 56 feet
2c) Exactly 24 times greater
Explanation:
1)
4x5.5 = 22
full circle = (5.5²)(π) = 95
(30/360)(95) = 7.92
95+7.92 = 102.92 m²
2a)
Perimeter = (2)(6+8) = 28 inches
2b)
Actual perimeter = (2)(144+192) = 672 inches or 56 feet
2c)
(24)(28) = (2)(144+192)
672 = 672
Exactly 24 times greater
