Answer 2

Answer:

942.85 cm^2

Step-by-step explanation:

Angle covered in 60 minutes=360 degree

Angle in 1 minute=360/60

Angle covered in 45 minutes=360/60 x 45=270 degree

Area described by the minute hand between 8am and 8:45 am=Area of a sector =Ф/360 x $\pi$$r{2}$

=270/360 x 22/7 x 20 x 20

=6600/7

=942.85 $cm^{2}$
