Yes the answer I should be 10.
Answer:
Perimeter = 101.2 cm
Step-by-step explanation:
The given figure has a length of 18 cm and width of 24 cm. A rectangle of length 8.6cm has been cut out, however, the question is asking to find the perimeter, or distance around the figure. The overall rectangle still has a perimeter of 18 + 18 + 24 + 24 = 84. However, now it also has two additional sides of 8.6cm each, so 8.6 + 8.6 = 17.2.
Add all the sides together for perimeter:
84 + 17.2 = 101.2 cm
Circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile
The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi
