Answer 1

Answer:

sorry it's too hard can I get a picture of your question

Answer 2

Answer:

Step-by-step explanation:

1)  3 rotations

i )  draw BC perpendicular to line A

   so in triangle ABC by paythagoras theorem,

   AC=50 cm

ii )  Radius of large circle= 50 + 25 = 75

iii )    circumference of large circle  =2 pie r

                                                    =2  *  3.14 * 75

                                                    =  471 cm

iv )  circumference of small circle= 2 pie R

                                                   = 2 * 3.14 * 25

                                                   = 157 cm

v )  no. of rotations = 471 / 157 = 3 rotations
