Find the length of the radius of circle c a. r=1 b. r=3 c. r=12 d. r=15

Option D. r = 15 units

Step-by-step explanation:

In this question Length of arc is given as s =

and angle inscribed at the center is θ =

By the formula s = rθ

By placing the values of s and θ we can get the length of radius

r =

r = = 15 unit

Therefore, Option D. r = 15 will be the answer.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
