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

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
