Question

help.... why is this problem so hard

Answer 1

Answer:

• 26

Step-by-step explanation:

The radius is given, but the circumference is π times the diameter. The diameter is twice the radius, so is 26.

26 goes in the green box.

Answer 2

Answer:

The number in the green box should be 26.

Step-by-step explanation:

This is not hard. You just apply the formula for the circumference of a circle.

C = 2 π r   where r = radius.  Here the radius is 13 so the circumference is

2* π * 13

= 26π   (answer)
