If the arc on a particular circle has an arc length of 12 inches, and the circumference of the circle is 48 inches, what is the angle measure of the arc?

Question

amistre64 · Answer

what is the angle of a full circle?

anonymous · Answer

360

amistre64 · Answer

good then:

48 is to 360

as

12 is to, the angle of the part we need

48x = 12,   will gives us  360x = angle we need,

solve for x for the solution.

so is it 90?

amistre64 · Answer

the angle is 90 yes. since x = 1/4,  360/4 = 90

So @amistre64 , If the arc on a particular circle has an arc length of 3 feet, and the angle measure of the arc is 60°, what is the circumference of the circle?

amistre64 · Answer

would you agree that we have 60/360th of a circle?

anonymous · Answer

yes so i would divide 360 by 60 which is 6 then multiply 3 by 6 which is 18 so the circles circumference is 18
