Answer:
Step-by-step explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³
Answer:
190 inches squared
Step-by-step explanation:
You have to split the shape into two different rectangles. Then multiply 22 x 5 to get the area of the right rectangle. The area of this is 110 inches squared. Then you find the area of the other rectangle by solving (15-5) x 8. You get 80. Then add 80 + 110 to get 190.
Hope it helps!
Required equation is y - y1 = m(x - x1); where m = 4 and (x1, y1) = (4, -4)
y - (-4) = 4(x - 4)
y + 4 = 4(x - 4)
