Awheel has a radius of 10 cm. approximately how far does it travel in 3 revolutions? a) 47.1 cm b) 94.2 cm c) 188.4 cm d) 376.8 cm

C) 188.4 cm

Step-by-step explanation:

In order for you to know how far a wheel travels in 3 revolutions, you need to know the circumference of it. A revolution equals the value of the circumference.

The formula to obtain the circumference of the circle is:

π * diameter

Moreover, to obtain the diameter, you need to multiply the radius times 2.

Therefore,

π * 2 (radius) = π * 2(10)

π * (20) = 62.8

The circumference of the circle is 62.8 cm.

Then,

3 * 62.8 = 188.4

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
