What is the perimeter of the track in meters use TT= 3.14 and round to the nearest hundredth of a meter
Sonja [21]

Answer:

P = 321.3m

Step-by-step explanation:

To help simplify the process of solving this problem, first break it up into different shapes. Here, you have two shapes: a rectangle and a circle (1 semi-circle + 1 semi-circle = 1 circle).

Next, use the equation for circumference of a circle to find the first part of the perimeter (C = πd). In this case, the diameter would be 45m.

  1. C = πd
  2. C = 3.14 × 45
  1. C = 141.3 m

This is the first part of the circumference. Now, you must consider the rectangle. (Because the two shorter sides of the rectangle are not part of the perimeter, do not include these in your final answer.) The length of the rectangle is 90 meters, and since both sides that measure to 90m are part of what makes up the perimeter, lastly add these to the circumference you calculated earlier.

  1. (90 + 90) or (90 × 2) = 180
  2. P = 141.3 + 180
  3. P = 321.3m

Hope this helps! : )

Find vale of x ASSAP
Blizzard [7]

Answer:

x = 127°

Step-by-step explanation:

in each triangle, the value of each exterior angle is equal to the sum of its two non-adjacent interior angles..

47° + 80° = 127°

or

the third angle in the triangle:

180° - (47° + 80°) = 53°

exterior angle:

180° - 53° = 127°
