Diameter of the bigger semi-circle is 15 m
circumference of the bigger semi-circle = πd = 15π
diameter of the smaller semi-circle = 15 - 2(1.25) = 15 - 2.5 = 12.5 m
circumference of the smaller semi-circle = πd = 12.5π m
Total length of the segments between the two circles = 11(1.25) = 13.75 m
Total length of wrought iron used = 15π + 12.5π + 13.75 = 100 m
Answer:
How do we find two equivalent ratios by using multiplication and division? ... to a given ratio we multiply or divide both the terms of the given ratio by the same non-zero number. ... Note: In this question we can't apply division method to get the answer in integer form because the G.C.F. of 4 and 5 is 1. ... All Rights Reserved.
Step-by-step explanation:
100% = 70
1% = .7 (divide by 100)
12% = 8.4 (Multiply 1% by 12)
70 - 8.4 = 61.6 (New Price)
Hope this helped! Got any questions just ask!
The y-intercept would be 25, if you want to find the y-intercept, plug in zero for x!
Answer: 15.7 (1 decimal place)
Step-by-step explanation:
The formula for the circumference of a circle is d(diameter) x π(pi).
The diameter of this is 5 so you would do 5xπ=15.7 (1 decimal place)
