The japanese 5 yen coin has a hole in the middle. the diameter of the coin is 22 mm and the diameter of the hole is 5 mm. what is the difference between the outer edge and the inner edge of the coin? if necessary, round your answer to the nearest tenth. 26.7 mm 53.4 mm 69.1 mm 84.8 mm

To find the difference between the outer and inner edges of the coin, you would calculate the circumference of the coin, C= 22π, and the circumference of the hole, C = 5π. Then you would subtract to find the answer, 22π − 5π = 17π.

b or known as 53.4

Step-by-step explanation:

got it wrong so just wanted to help

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
