Answer:
For any circle of radius r
The diameter of the circle = two times of the radius = 2r
And The Circumference= C = 2πr
14. If r = 8
So, d = 2r = 2 * 8 = 16 cm
C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)
15. If d = 9 m
So, d = 2r
∴ r = d/2 = 9/2 = 4.5 m
And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)
Answer:
72cm
Step-by-step explanation:
6cm times 24cm divided by 2
Answer:
E
