Question:

The circumference of a clock is 22 inches. What is the radius of the clock?

Answer:

Radius = 3.5 inches

Solution:

Shape of the clock is circle.

Circumference of the circle = 2πr

Circumference of a clock = 22 inches

\Rightarrow2\pi r=22

$\Rightarrow2\times\frac{22}{7}\times  r=22

$\Rightarrow\frac{44}{7}\times  r=22

$\Rightarrow  r=22\times \frac{7}{44}

$\Rightarrow  r=\frac{7}{2}

⇒ r = 3.5 inches

Hence the radius of the clock is 3.5 inches.

37 1/2 is what percent of 5
DanielleElmas [232]

Answer:

750%

Step-by-step explanation:

We know that 100% of 5 is 5,

200% of 5 is 10,

300% of 5 is 15,

400% of 5 is 20,

500% of 5 is 25,

600% of 5 is 30,

700% of 5 is 35,

800% of 5 is 40.

So 37 1/2 percent of 5 must be between 700 and 800 percent of 5. We also know that 2.5 is 50% of 5, and 35 + 2.5 = 37.5. So 37 1/2 is 750% of 5
