Answer:
1. Radius: 4
Area: 25.12²
2. Diameter: 10
Area: 31.4²
Step-by-step explanation:
Grade 5 pi = π3.14
1. 8÷2 = 4
3.14 x 4 = 12.56
12.56 x 2 = 25.12
Answer: 25.12 ²
Formula: π x r x 2
Check and Look Back: 3.14 x 8 = 25.12 ²
2. 5x2 = 10
3.14 x 10 = 31.4
Answer: 31.4 m²
Formula: π x d
Check and Look Back: 3.14 x 5 = 15.7
15.7 x 2 = 31.4 m²
