Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
The geometric sequence is 3, 9, 27, 81, 243, 729 because each time it is multiplied by 3.
Answer:1/10
Step-by-step explanation:
Answer:
The largest angle is 63
Step-by-step explanation:
Shows that one is 36 degrees larger: 63 - 36 = 27
Shows that the angles are complementary/Their sum is 90: 27 + 63 = 90
