A student solved for the radius of a circle with a circumference of 12π Step 1: C = 2 pi r. Step 2: 12 pi = 2 pi r. Step 3: Star
Greeley [361]

Answer:

The student made a mistake in step 4

The length of the radius should be 6 cm

Step-by-step explanation:

Let us write each step to find the radius of a circle from its circumference

Step 1:

∵ C = 2πr

∵ C = 12π

Step 2:

Equate 12π by 2πr

∴ 12π = 2πr

Step 3:

Divide both sides by 2π

∵ \frac{12\pi }{2\pi }=\frac{2\pi r}{2\pi }

Step 4:

∴ 6 = r

∴ The radius of the circle is 6 cm

The student mad a mistake he divided the left hand side by 2π and the right hand side by 2 only he left π with r

Step 4:

∴ 6 = πr

So he divided both sides again by π

Step 5:

∵ \frac{6}{\pi }=\frac{\pi r}{\pi }

Step 7:

∴ \frac{6}{\pi } = r

The student made a mistake in step 4

The length of the radius should be 6 cm

stiks02 [169]

Answer: n>320

Explanation:

Let's solve your inequality step by step.

Step 1: Simplify both sides of your inequality

n/-8 < -40

-1/8n < -40

Step 2: Multiply both sides by 8/(-1).

(8/-1)*(-1/8n)< (8/-1)*(-40)

n>320
