Can someone tell me if this is right for the arc

BC is a minor arc

Step-by-step explanation:

Just as an extra piece of information that can help us:

Knowing that the diameter splits a circle into halfs, it's degree measure is half of the degree measure of the whole circle: 360/2 = 180 degrees.

This means that diameter AC consists of a 180 degree measure, helping us in the sense that:

mBC + mBA = mAC

mBC + 70 = 180

mBC = 180 - 70

mBC = 110 degrees

Now the mBC to the mBEC is 110: 250 such that we know arc BC is smaller in size as degree measure is proportional to circumference length. Knowing it is smaller in length, BC is thus a minor arc.

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

the correct answer is 1: 2

hope this your welcome : )
