65.77π x 663.23455π / 9π
= (65.77 x 663.23455 / 9) π
= 4,846.770706... π (rounded)
= 15,226.57924 (rounded)
2. is 45° it’s showing a 90° cut in half, since it’s congruent, it’s gonna be 45°…
3. False
Answer:
N: n = 5 sides
side length: a = 23.2 m
inradius: r = 15.966 m
circumradius: R = 19.7351 m
Area: A = 926.03 m2
perimeter: P = 116 m
interior angle: x = 108 °
exterior angle: y = 72 °
Description:
We use the calculations on the shape 16 and 23.2. Side length is 23.2. Pi is 16. calculate the numbers and all the answers are added above.
