A cylinder has a height of 5.3 cm and a diameter of 3.0 cm. What is its volume? (Hint: Volume of a cylinder = r2h ) 25.0 cm3 66.2 cm3 149.9 cm3 37.5 cm3

37.5 cm³ .

Step-by-step explanation:

h = 5.3 cm

diameter = 3 cm

r = 3/2 = 1.5 cm

Volume of cylinder = πr²h   {Plug in the values of h & r }

                               = 3.1428 * 1.5 * 1.5 * 5.3

                               = 37.5399

                               = 37.5 cm³

The circle is centered at (5, −7) and has a radius of 7.

Step-by-step explanation:

The standard form of the equation of a circle with center (a,b) and radius r is given as:

The given equation is

We rewrite to look like the stay form:

We now compare the two equations to get:

a=5, b=-7 and r=7.

Therefore the circle is centered at (5,-7) and has a radius of 7
