Question

What is the approximate circumference of the circle that has a center at (2, 1) and passes through the point (7, 1)? A 10 units B. 16 units С 31 units D 79 units​

Answer 1

Answer:

C. 31 units

Step-by-step explanation:

Circumference of a circle is the distance around the circle and is given by C = pi•d

Your circle with a point and center given has a radius of 5 because from (2,1) to (7,1) is 5 units. Radius 5 means the diameter is 10.

C = pi•10

= 3.14•10

= 31.4 using 3.14 as an approximation for pi.

Circumference is approximately 31 units.

Answer 2

It’s c.31 units
