In the dimension of the frisbee given to be 10.2 inches in diameter, there are three significant figures. All, from 1, 0 and 2. Since these values are all significant, the last digit determines the greatest possible error allowed that is only in the tenths digit. The circumference of the frisbee is calculated through the equation,
C = πD
Substituting,
C = π(10.2 in) ≈ 32.0 in
Answer: the first answer is 8 and 5/8, #2, (bottom left) is 17 and 6/10. #3, (top right) is 6 and 3/8. #4, (bottom right) is 19 and 3/10.
Step-by-step explanation: to add fractions, you have to have a common denominator. to get a common denominator, you multiply one or both sides to make the same number on the bottom. when you multiply the bottom, you also have to multiply the top. After that, you add the top numbers and add the whole numbers next to it. Then you just put the numbers together.
Hope this helps! if it is wrong, could you please correct me.
