circle area = pi * radius^2
if diameter = 10 then radius = 5
circle area = pi * 5^2
circle area = pi * 25
circle area = 78.5398163397 square units
step-by-step explanation:
answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°
so ac is the half of 24=12ft,and from the pythagorean theorem we find ba
ba=√bc^2-ac^2=√576-144=√432=12√3ft
so bac is 12+12√3=12(1+√3)ft
well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
i believe it is 2
