Answer:

Step-by-step explanation:
Using the ratio equality for circles
 =
 = 
(a)
Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus
 =
 =  =
 =  ( cross- multiply )
 ( cross- multiply )
3C = 180 ( divide both sides by 3 )
C = 60 mm
(b)
Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus
 =
 =  ( cross- multiply )
 ( cross- multiply )
225C = 1188 ( divide both sides by 225 )
C = 5.28 cm
 
        
             
        
        
        
Answer:
Step-by-step explanation:
10^4 = 10000
1.7 × 10^4 = 1.7 × 10000
 = 17000
10^-2 = 1/10^2= 1/100
8.5 × 10^-2 = 8.5 × 1/100
 = 17/200
Final answer = 17000 × 17 / 200
 = 1445
