A rectangular tank with length 50cm and width 30cm contains 36litres of water. A block is placed in the tank and the water level rises by 1cm. Show that it simplifies to x^2+5x-300=0

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

r = 78539458390583095803458309458039485093485 or just 3
