Answer 1

Heya

______________________________

in one hour the minute hand will cover a complete circle having radius 4cm

So, it's area is = π × ( 4 )² = 50.28cm²

Answer 2

Answer:

50.26548

Step-by-step explanation:

radius(r) = 4 cm

Area of a circle = πr²

As time = 1 hour = 60 minute = 1 complete rotation

Thus substitute the values in the formula

$\pi *4^{2}\\ =16\pi \\=\frac{22}{7}*16\\= 50.26548\\This...is...only...approximated...value$
