Answer:
Circumference = dπ
1. 11×2=22•3.14= 69.08cm
2. 16 is the diameter so 16•3.14 = 50.24cm
3. 10×2=20•3.14= 62.8cm
4. 8×2=16•3.14= 50.24cm
5. 24 is the diameter so 24•3.14 = 75.36
Area = πr²
Area = πr² (the final answer of area must be cm²)
1. (3.14)(11)² = (3.14)(121)= 379.94cm²
2. (3.14)(4) (4 because the diameter is given so it's should be the radius) (3.14)(4)²= 50.24cm²
3. (3.14)(10)² = (3.14)(100)=314cm²
4. (3.14)(8)² = (3.14)(64)= 200.96cm²
5. (3.14)(12)² (12 because 24÷2=12) = (3.14)(12)²= 115.74cm²
