If the diameter is d = 8, then we divide that in half to get the radius of r = 4.
If the radius is r = 9, then we double it to get the diameter of d = 18
The formulas are:
I'll let you determine the others.
Answer:
Step-by-step explanation:
Diameter is twice the radius. d = 2*r
Radius is half the diameter r = d÷2
1) d = 8
r = 8÷ 2
r = 4
2) r = 9
d = 2*r
= 2*9
d = 18
3) r = 24
d = 24*2 =48
4) d = 36
r = 36 ÷2 = 18
5) d = 52
r = 52÷2 = 26
