Question

Plz do this i will mark you brainlist and thats for 70 points!!!!​

Answer 1

Answer:

First find the circumference of both wheels

C = pi d

Large wheel = 3.14 * 60

                     = 188.4

Small wheel = 3.14 * 18

                     = 56.52

Divide them both with divide 600 by the circumference

Large wheel = 600/188.4 = 3.18 or 3 rotations

Small wheel = 600/56.52 = 10.61 or 11 rotations

b. 2 large wheels. This is because you can cover more distance with large wheels that small wheels. Large wheels are also worth the energy.

Hope this helps

Answer 2

Answer:

A: The large tire makes 3 rotations, and the small tire makes 11 rotations.

B: This part of the answer you answer because its asking for your opinion! ;)

Step-by-Step Explanation:

You must find the circumference of the big tire, and the small tire.

C=$\pi$d

The large tire this means:

$C= 3.14(60)=188.4$

Dividing 600/188.4 we get 3 rounded to the nearest whole number.

For the small tire:

$C=3.14 (2*9)=3.14(18)=56.52\\Dividing 600/56.52, we get to the (nearest whole number), 11 small tire rotation.$
