Question

A student was trying to calculate the circumference of a circle with a radius of 5 ft. The student’s work is shown below. Which statement is true?

Student’s scratch work: C = 2.5(3.14) = 7.85 in.

 

Group of answer choices

 

(A.) They calculated the circumference right because C= 7.85 in.

 

(B.) They did not calculate the circumference right because it should be C = 2(5)(3.14) which would make the circumference 31.4 in.

 

(C.) They did not calculate the circumference right because it should be C = 5(5)(3.14) which would make the circumference 78.5 in.

 

(D.) They did not calculate the circumference right because it should be C = 10(10)(3.14) which would make the circumference 314 in.
