Question

the length of a minute hand of a clock is 14 cm find the area swept by the minute hand in 10 minutes

Answer 1

radius=14cm
area swept by minute hand=10mins
{60 minutes=360 degrees
1 minute =360/60 =6 degrees
for 10 minutes 6×10 =60 degrees}
so angle described by minute hand in
10mins, theta =60degrees
so area swept in 10 mins =πr² theta/360
=22/7×14×14×60/360
=308/3
=102 2/3( in mixed fraction)
pls mark it brainliest

Answer 2

Hey!

____________________________

Radius= 14cm
Area swept in 10 minutes =?

We know,

60 min= 360°
1 min = 360/60= 6°

10 min = 10×6=60°

Area swept in 10 min= πr^2 θ/360
= 3.14×14×14× 60/360
=308/3
