Area of a pyramid = 1/3(area of base x height)
area of base = 6(1/2(4 x 2√3)) = 24√3
height = sqrt(6^2 - (2√3)^2) = sqrt(36 - 12) = sqrt(24)
Area of the pyramid = 1/3(24√3 x √24) = 8√72 = 48√2 square feet.
Answer:
width of a river = 45m
Step-by-step explanation:
ration and proportion
let x = width of a river
x 20.9 m
------ = --------
56 m 26 m
x = (20.9 * 56) / 26
x = 45 m
therefore the width of a river is 45 m
Answer:
the point (9,-12) is also on the line
Step-by-step explanation:
by using the 2 points the equation is y=-4/3x
use x of 9
y = -12
it will also represent a direct variation function
so two of the 4 will be correct
