Jonathan has a cylindrical fish tank that is one foot tall. The diameter of the fish tank is 10 inches. How much glass did it take to make the tank?

942 in^3

Step-by-step explanation:

We are to calculate the volume of the cylinder

volume of a cylinder = nr^2h

n = 22/7

r = radius = 10/2 = 5

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

height = 1 foot = 12 inches

3.14 x 5^2 x 12 = 942

what’s the question?

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
