Given the diameter of a circle, we can find its radius by dividing the diameter by 2, like this:

r=\frac{d}{2}

Where r is the radius and d is the diameter of the circle, by replacing 30 for d, we get:

r=\frac{30}{2}=15

Then, the radius of this circle equals 15 m

NeTakaya

Step-by-step explanation:

15a)

x^2+4x=21               Subtract both sides by 21

x^2+4x-21 =0
