This problem can be solved easily using a proportion:
3\frac{2}{3}  - 1
x - 3\frac{1}{4}

So, x= \frac{3\frac{2}{3} * 3\frac{1}{4}}{1}=3\frac{2}{3} * 3\frac{1}{4}=\frac{11}{3} * \frac{13}{4}=\frac{11*13}{3*4}=\frac{143}{12}=11\frac{11}{12}

The answer:  11\frac{11}{12} cups are needed.

A spherical cantaloupe is cut in half. The visible cross-section has an area of 5252 in2. The volume of the cantaloupe is _____
artcher [175]

Answer:

V = 286319.465 cm3

Step-by-step explanation:

First, you have to find the radius to be able to find the volume of a sphere.

The equation for the area of a circle is pi r^2 so you have to so some algebra.

5252 = pi r ^2

5252/pi = r^2

1671.76352 = r^2

sqrt(1671.76352) = r

r = 40.8872048

then you do the equation for the volume of a circle which is 4/3 pi r^3

4/3 pi (40.8872048)^3

4/3 pi 68353.7373

4/3 214739.599

286319.465

V = 286319.465 cm3
