Question

Pls answer fast with explanation i will mark as brainliast.​

Answer 1

Step-by-step explanation:

10) ⇒ r=14 cm

total area= πr²

=22/7*196=616 cm²

r2= 3.5 cm

area of the small circles= 2*πr²=2*12.25*22/7=77 cm²

length of rectangle=3

breadth=1

area =lb=3 cm²

area of the small circles+area of rectangle=77+3=80 cm²

remaining area=616-80=536 cm²

11)⇒ Since the question says how much it moves in 1 hour

Therefore;

The distance moved by min hand= Circumference

                                                       =2*pi*r

                                                        =2*3.14*15 cm

                                                    =94.2cm

if this is helpful to u then mark me as brainliest
