Question

What’s the diameter of this object?

Answer 1

1.6 feet

Explanation:

The diameter is twice the radius, or

d=2r

The line on the object indicates the radius, so the radius is 0.8. Substitute 0.8 in for r

d=2*0.8

Multiply

d=1.6

So, the diameter is 1.6 feet

Answer 2

1.6 feet

Explanation:

The radius is 1/2 of the diameter.

0.8 * 2 = 1.6
