Acircle has a circumference of 85 units. approximate the diameter of the circle. 14 units 27 units 54 units 170 units

 The correct option is (B) 27 units.

Step-by-step explanation: Given that a circle has a circumference of 85 units.

We are to find the approximate length of diameter of the circle.

The circumference of a circle with diameter d units is given by

In the given circle, we have

C = 85 units,  diameter, d = ?

So,

Thus, the approximate length of the diameter is 27 units.

Option (B) is CORRECT.

the radius is 2 times the diameter.

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
