Question

I need this asap plsss help me!!!!!​

Answer 1

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:

• radius = diameter/2
• diameter = 2*radius

I'll let you determine the others.

Answer 2

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
