Answer:
50.24 in
Step-by-step explanation:
to find how far it it will go you will need to find the circumference and times it by 2 to find the circumference the formula is 2*pi*radius so you would do 2*3.14*4 and that is 25.12 but since it is 2 revolutions you times 25.12 by 2
Answer:
11.33 in. to the nearest hundredth.
Step-by-step explanation:
The perimeter of the shaded area = length of the 2 straight lines + the length of the 2 arcs = 4 + length of the 2 arcs.
Calculate the length of the outer arc:
This equals (30 / 360) * perimeter of the largest circle
= 1/12 * 2 π * 8
= 4/3 π in.
The inner circle has a radius of 8 - 2 = 6 ins
so the length of the inner arc
= 1/12 * π * 2 * 6
= π in.
So the perimeter of the shaded region = 4 + 4/3 π + π
= 4 + 7π/3
= 11.33 in.
The length is 25.
Do 7 × 2 = 14, then 64 - 14 = 50. Then do 50 ÷ 2 to give you 25.
Note that Cougars have a ratio of 12:10, or 1.2, whereas
Bobcats have a ratio of 20:10, or 2. So the Bobcats did best!
