Answer
Success!
r = 2.5
C = 5π or 15.708
A = 6.25π or 19.635
C = 5π or 15.708
A = 6.25π or 19.635
↓Steps Explained:↓
A circle has diameter = 5
Calculate Area, Circumference, Radius, Diameter
Calculate radius (r):
d = 2r
Rearranging the equation, we get:
| r = | d |
| 2 |
| r = | 5 |
| 2 |
r = 2.5
Calculate circumference (C):
C = 2πr
C = 2π * 2.5
C = 5π or 15.708
Calculate Area (A):
A = πr2
A = π * 2.52
A = 6.25π or 19.635
Final Answers
r = 2.5C = 5π or 15.708
A = 6.25π or 19.635
