Question

3. Suppose the radius of the larger circle is r. What is its diameter?
d2 =
R2

Answer 1

2R

Explanation:

The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.

Answer 2

2r

Explanation:

You suppose that the radius of a larger circle = r

so diameter = r*2 = 2r

aint really sure tho
