Answer: 86.5 in²
Step-by-step explanation: Circumference is2·pi·r= 32.97 in.
Radius r = 32.97 in/ 2pi = 5.247 in. Area is pi·r²
Angle of elevation of the sun: 69 degrees
Step-by-step explanation:
tan(x) = 200/75
x = tan^-1 (200/75)
x = 69 degrees
Then there are 210 people since 8+7+195 = 210
Discriminant = sq root (-17^2 -4*3*10)
discriminant = sq root (289 -120)
discriminant = sq root (169)
The discriminant is positive so the equation will have 2 rational solutions.
