6 0

Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

C=2\pi r

So we can substitute 7 for r and 3.14 for pi:

C=2(3.14)(7)=43.96 cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.

The ratio of the measures of the sides of a triangle is 3:4:5. Its perimeter is 48 inches. Find the scale factor as a decimal, a
Trava [24]

Given:

The ratio of the measures of the sides of a triangle is 3:4:5.

Its perimeter is 48 inches.

To find:

The scale factor as a decimal, and the measure of each side of the triangle.

Solution:

Let x be the scale factor. Then the measures of sides of the triangle are 3x, 4x and 5x.

The perimeter of the triangle is 48 inches. It means the sum of all sides of the triangle is 48 inches.

3x+4x+5x=48

12x=48

Divide both sides by 12.

x=\dfrac{48}{12}

x=4

Now, the measures of sides are:

3x=3(4)

3x=12

Similarly,

4x=4(4)

4x=16

And,

5x=5(4)

5x=20

Therefore, the scale factor is 4 and the measures of sides are 12, 16 and 20.
