Question

the length of hour hand is 5 cm the area swept by the hour hand in one hour​

Answer 1

Answer:

A≈78.54 sq. cm

Step-by-step explanation:

The area covered will be area of circle with radius 5 cm.

A=πr^2

  =π·5^2

   ≈78.53982

Answer 2

Answer: 78.5cm²

We know that the hour hand moves in the shape of a circle, so

area of circle = πr²

here the hour hand works as the radius

(we don't need to find the area by using the sector formula since 1 hour means basically a whole round)

so

πr² = 22/7 x 5 x 5

     = 550/7

     = 78.5cm²

Hope this was clear and helpful

I hope to clear more of your questions in the near future
