Answer:
Step-by-step explanation:
Radius of clock is 15 cm
A = πr²
C = 2πr
~~~~~~
C = 2π×15 = 30π
C = 2(22/7)15 ≈ 94.3 cm
94.3 ÷ 60 × 35 ≈ 55.0 cm
The tip of the hand moves 55.0 cm during 35 minutes.
A = π × 15² = 225π
A ≈ 707.14 cm² ( π = 22/7) [or ≈ 706.5 cm² if π ≈ 3.14]
The area of a clock is 707.14 cm²
P.S. Please pay attention to suggestion for "π" in the task. It can be 3.14 or it can be 22/7.
