Step-by-step explanation:
<u>Circle 1</u>
- Circumference = 2πr = 2 x 3.14 x 2.5 = 5 x 3.14 = 15.7 m
- Area = πr² = 3.14 x (2.5)² = 3.14 x 6.25 = 19.625 m²
<u>Circle 2</u>
- Area = πr² = 3.14 x 1² = 3.14 mm²
- Circumference = 2πr = 2 x 3.14 x 1 = 6.28 mm
Answer:
circumference with diameter 5=15.7m
area with diameter 5=19.625m²
