Find the midpoint of diagonal WY.. . Figure WXYZ is shown. W is at 0, 2. X is at 0, 6. Y is at 6, 6. Z is at 6, 2.. . (2, 4). .
Anestetic [448]

Answer:

(3,4)

Step-by-step explanation:

we know that

The formula to calculate the coordinates of the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have that

The coordinates of diagonal WY are

W(0,2), Y(6,6)

substitute in the formula to calculate the midpoint

M(\frac{0+6}{2},\frac{2+6}{2})

M(\frac{6}{2},\frac{8}{2})

M(3,4)

a cylinder and a cone have the same volume. the cylinder has a radius of 2 inches and height of 3 inches. the cone has a radius
kaheart [24]

Answer:

Step-by-step explanation:

Volume of a cylinder = pi*(xx)^2*yy

= x^4*pi*yy

Volume of a cone = 1/3*pi*(9x^2)^2*h

= 27pi*x^4*h

x^4*pi*y^2 = 27pi*x^4*h

h = y^2 / 27
