Question

HELP ASAP PLEASE!!!(DUE TOMORROW!!!) (btw number 9)

Answer 1

Game 1
Circumference=Diameter × pi
Circumference=27.3×3.14
Circumference=85.722
Circumference~=86 cm

Game 2
Circumference= Diameter × pi
Circumference=22.5 × 3.14
Circumference=70.650
Circumference~=71cm

Game 1- Game 2
86-71
15
Thus the circumference of the flying disc the first game is 15cm greater that that of game 2.


NOTE: ~= is about OR approximately equals

Answer 2

First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65＝85.722 and 2*3.14*11.25＝70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.
