Answer:

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

Answer:

The smallest possible perimeter of the triangle, rounded to the nearest tenth is 72.4 in

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ------> the length of  the remaining side

Applying the triangle inequality theorem

1) x+x > 30

2x > 30

x > 15 in

The perimeter is equal to

P=30+2x

<em>Verify each case</em>

1) For P=41.0 in

substitute in the formula of perimeter and solve for x

41.0=30+2x

2x=41.0-30

x=5.5 in

Is not a solution because the value of x must be greater than 15 inches

2) For P=51.2 in

substitute in the formula of perimeter and solve for x

51.2=30+2x

2x=51.2-30

x=10.6 in

Is not a solution because the value of x must be greater than 15 inches

3) For P=72.4 in

substitute in the formula of perimeter and solve for x

72.4=30+2x

2x=72.4-30

x=21.2 in

Could be a solution because the value of x is greater than 15 inches

4) For P=81.2 in

substitute in the formula of perimeter and solve for x

81.2=30+2x

2x=81.2-30

x=25.6 in

Could be a solution because the value of x is greater than 15 inches

therefore

The smallest possible perimeter of the triangle, rounded to the nearest tenth is 72.4 in
