Find the radius of a circle with the given circumference. 15 ft. r = a.30 ft. b.30 ft. c.7.5 ft. d.7.5 ft.

Step-by-step explanation:

We know that , the circumference of a circle is given by :-

, where r is the radius of the circle.

Formula for radius :  

, where C is the circumference of the circle.

Given : Circumference of circle = 15 ft.

Then , the radius of a circle will be :-

Hence, the radius of a circle=

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
