The arc length is the measure of the distance along the curved line making up the arc<span>. It is longer than the straight line distance between its endpoints. To calculate this we simply multiply the angle to the circumference of the circle. It is expressed as:
Arc length = 2</span>πr(angle / 360)
Arc length = 2πr(50 / 360)
Arc length = 5πr / 18
Just multiply the radius then you're good. Hope this helps. Have a nice day.
Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
Make G the subject
Substitute 25 + U for G in the third equation
Collect Like Terms
Substitute 38 for U in
Substitute 63 for G in
circumference= 2(pi)r OR (pi)d
d is diameter and r is radius
if the circumference is given, then you would have to work backwards.
in this case, Circumference = 78.5 ft
the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r
next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d
hope this helps! make brainliest please
