Which of the following formulas could be used to determine the volume of a cone stacked on top of half a sphere?
Select all that apply.
V = lwh
V = Bh
V = 1/3 Bh
V = pi r^2h
V = 1/3 pi r^2h
V = 4/3 pi r^3

i think the amount would be $140.62

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

the answer is -81 is the answer
