Step-by-step explanation:
This seems like you just want to figure out the circumference of the manhole cover. The formula for the circumference of a circle is pi (3.14) multiplied by the diameter (d) of the circle so, circumference=πd. (π is the symbol for pi and approx. equals 3.14)
Circumference = πd
= 3.14(d)
= 3.14(3)
= 9.42 ft.
The length of the brass grip-strip will be 9.42 ft.
If the problem was stated in terms of the radius of the manhole cover then the formula would be circumference = 2πr which is the radius multiplied by 2 then multiplied by pi.
The radius of a circle is the distance from the center to the edge and the diameter is the distance from one edge of the circle to the other passing through the center of the circle.
Well, if the grip strip were of no width and could be straightened out to a line (which a piece of rubber cut in a circle couldn't be), then the length of the grip would correspond to the circumference of the manhole cover.
Circumference = 2*PI*radius = PI*diameter so your answer is 3*PI feet long.
Answer:
you get 6.90372 so i thnk it is clse to B
Answer: Determine the measures of ∠ L and ∠ M . The figure shows a triangle UpperWord LMN. Sides UpperWord MN and UpperWord LN of this triangle are produced to points Upper O and Upper P respectively. The angle UpperWord ONP is labeled as 48 degree, angle UpperWord NLM is labeled as x, and the angle UpperWord LMN is labeled as x.
