What is the diameter of this circle if the circumference is 30 pi inches? A circle. C = 30 pi in. 15 in. 30 in. 45 in. 60 in.

30 inches

Step-by-step explanation:

The circumference of a circle can be found using:

c=πd

The circumference is 30π inches. Substitute 30π in for c.

30π=πd

The question asks for the diameter. We have to solve for d. π and d are being multiplied. To reverse this, divide both sides by π, because division is the opposite of multiplication.

30π/π=πd/π

The πs on the right and on the left will cancel out.

30π/π=d

30=d

The diameter is 30 inches

the answer is 62

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
