Step-by-step explanation:
diameter: 8
radius: 4
height: 18

Answer:
see explanation
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 )
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 )
225C = 1188 ( divide both sides by 225 )
C = 5.28 cm
Answer:
The same (42 degrees)
Step-by-step explanation:
This is because the angles are congruent or the same.
For number 5, the answer is B.
For number 6, the answer is B.
