Question

the minute hand of a clock is 14cm . find the area swept by the minute hand is 15 minute​

Answer 1

Answer:

154

Step-by-step explanation:

Hence the area swept by the minute hand clock in 1 min =61660 square centimetres. Hence the area swept by the minute hand of the clock in 15 minutes =61660×15=154 square centimetres, which is the same as obtained above.

Answer 2

Answer:

the minute hand of a clock is 14cm

so r=14cm

thetha=90°

area swept =thetha/ 360°×πr²

=90°/360°×(22/7)×14²

=1/4×22(14)(2)

=154cm²
