find the approximate value of the circumference of a circle with the given radius. use = 3.14. round your results to one more decimal than in the given radius.6 ft.c =

pi x^2

step-by-step explanation:

pi times x squared

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
