Area of rectangle = Length*Width
Area of rectangle = 13*9
Area of rectangle = 117
------------------------
The area of a circle formula is
A = pi*r^2
where A is the area of the circle and r is the radius
If the area of the rectangle is equal to the area of the circle, then we can replace the "A" with 117 and solve for r. We'll use 3.14 in place of "pi"
A = pi*r^2
117 = pi*r^2
117 = 3.14*r^2
3.14*r^2 = 117
r^2 = 117/3.14
r^2 = 37.2611464968152
r = sqrt(37.2611464968152)
r = 6.1041908961643
Double this radius to get the diameter
d = 2*r
d = 2*6.1041908961643
d = 12.2083817923286
d = 12.2
------------------------
Answer: the diameter of the round pan should be approximately 12.2 inches
That just means that you are dividing by -3 so when you do 45 divided by -3 what do you get?
V = 4/3 * (pi) * r^3
V = 4/3 * (pi) * 10^3
V = 4/3 * (pi) * 1000
V = 4000/3(pi)
V = 1333 1/3 (pi) in^3 <==
