Find the circumference of the circle with the given radius or diameter. (use 3.14 for π.) radius = 30 cm a. 188.4 cm b. 94.2 cm c. 2,826 cm d. 11,304 cm

a. 188.4 cm

Step-by-step explanation:

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

, where r is the radius of the circle.

Given : The radius of the circle : r= 30 cm

Then , the circumference of the circle is given by :-

Hence, the circumference of the circle = 188.4 cm

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
