Eli has a cylindrical rain water gauge by his garden that has a
diameter of 2 inches and a height is 8 inches. What is the volume of
water when the gauge is half full?
a 10 in
c. 16 in
b. 12.56 in
d 25.12 in

π×2²×8= 32π

but  probably the diameter is divided

π×1²×8= 15.12π

maybe the D is the correct answer.

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

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram
