Cavalieri's principle states that volume formulas for pyramids and cones will also apply to both right and oblique solids, a<span>s long as the "matching" cross section areas are equal.
So we can use the formula V=bh regardless of the resulting shape.
V = bh = </span>π(15 m)²(12 m) = 2700π m³ ≈ 8482.3 m³
Answer:
add the lengths of each side of the shape. If there are units, include units in your final result.
Step-by-step explanation:
add the lengths of each side of the shape. If there are units, include units in your final result.
Y = -x - 9
-x -2(-x-9)=-5
-x +2x + 18 = -5
x + 18= -5
x= -23
-23+ y = -9
y= 14
Answer:
(5, 0)
Step-by-step explanation:
Se the equations equal
x² - 2x - 15 = 8x - 40
Subtract 8x from both sides
x² - 10x - 15 = -40
add 40 to both sides
x² - 10x + 25 = 0
Factor
(x - 5)(x - 5) = 0
x = 5
---------------
plug in x = 5 into
y = 8x - 40
y = 8(5)- 40
y = 0
-----------------
Solution
(5, 0)
