So we are trying to get the “y” alone, so to undo the division by -8, we will multiply both sides by -8, then simplify.
(-8) y/(-8) = (-8) 1/16
y = -8/16
and simplified:
y = -1/2
Volume of reg sq. pyramid = vp
vp = 1/3×s^2×h, where s = side and h = height
Volume of cone = vc =1/3×h×pi×r^2
Now we know that h is the same for both, and the cones diameter = s of square base, so radius (r) = 1/2 s
so now vc = 1/3×h×pi×(1/2s)^2
let's remove the same items for both vc and vp
so 1/3 and h
now let's plug an arbitrary number into each:
vc = pi (10/2)^2 = 3.14×25 = 78.54
vp = s^2 = 10^2 = 100
So any square pyramid has slightly more volume than the cone
Answer:
y = 3x -4
Step-by-step explanation:
The slope-intercept equation looks like this: . Where m is the slope of the function and b is the y-coordinate of the vertical intercept (where the function crosses the y-axis). Let's apply the formula:
Answer:
I get it now.
Step-by-step explanation:
The formula for volume of a cone = PI x r^2 x h/3
PI = 3.14
r = 8.5/2 = 4.25
h = 4.5
Volume = 3.14 x 4.25^2 x 4.5/3
Volume = 3.14 x 18.0625 x 1.5
Volume = 85.074375
Rounded to the nearest hundredth = 85.07 cubic cm.
