Answer:
b
because when you try to find the common denominator the lowest number is 40. so you then multiply the 2x8 and the 3x5 that gives you 16/40 + 15/40 = 31/40
V = Vcyl - Vcone
V = base×height - 1/3base×height
V = (pi×5^2)(16) - 1/3(pi×4^2)(12)
V = 1256 - 200.96
V = 1055.04 cubic cm.
I think it 48 i’m not sure
Answer:
a) well we know the hypotenuse and we know that all sides are 90 degrees, and that its an even square, so if we split it into a triangle , we know that the other 2 angles are 45 degrees total, with this we can calculate the other 2 sides, which round to 10 inches.
b) if we know the sides of the first side, knowing the fact that its a square we know that all sides are even, therefore, all sides are 10 inches, the formula the finding the perimeter is basic:
P=L(2) + W(2)
L being length, W being width and P being perimeter
so we add up all 4 sides, here is the equation:
10 + 10 + 10 + 10 = 10 x 4 = 40
With this, we know that the perimeter is 40 inches total
c) knowing how long the sides are, we can figure out the area through another basic formula:
A=L X W
With A meaning Area
since its a square, we know all the sides are even, so the width and length are both 10...
10 X 10 = 100
