Answer:

Option D

Step-by-step explanation:

We need the product of:

(-3s + 2t)*(4s - t)

We can use the distributive property:

(a + b)*(c + d) = a*c +b*c + a*d + b*d

Applying to our case:

(-3s + 2t)*(4s - t) = (-3s)*4s + (-3s)*(-t) + 2t*4s + (2t)*(-t)

(-3s + 2t)*(4s - t) = -12(s^2) + 3st + 8ts - 2(t^2)

(-3s + 2t)*(4s - t) = -12(s^2) + 11ts - 2(t^2)

So, the correct is option D negative 12 s squared + 11 s t minus 2 t squared

A cylindrial hole is cut through the cylinder below.
Vika [28.1K]

Answer:

V=1884 Cubic mm

Step-by-step explanation:

We know that the volume of the Sphere is given by the formula

V= \pi r^2h

Where r is the radius and h is the height of the cylinder

We are asked to determine the radius of the hollow cylinder , which will be the difference of the solid cylinder and the cylinder being carved out.

V=V_1-V_2

V=\pi r_1^2 \times h-\pi r_2^2 \times h

V=\pi \times h \times (r_1^2-r_2^2)

Where

V_1 is the the volume of solid cylinder with radius r_1 and height h

V_2 is the volume of the cylinder being carved out with radius r_2 and height h

where

r_1 = 7 mm ( Half of the bigger diameter )

r_2 = 5 mm ( Half of the inner diameter )

h=25 mm

Putting these values in the formula for V we get

V=\pi \times 25\times (7^2-5^2)

V=3.14 \times 25 \times(49-25)

V=3.14 \times 25 \times 24

V= 1884
