5. MERRY-GO-ROUND Mr. Lee is
putting trim around the edge of a
circular merry-go-round that has a
radius of 8 feet. How much trim
does he need to buy to the
nearest tenth?

50.30 ft

Step-by-step explanation: you have to multiply the radius by 2 to multiply it by 3.14 the answer is 50.24 but it's to the nearest tenth meaning you have to round it.

you'll have to round it up because if you round it down Mr. Lee won't hav enough trim

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the two may have that, even a breakdown is probably offered
