The sphere is centered in the cube. Find an expression for the volume of the cube outside the sphere
Nikolay [14]

Solution -

The sphere is centered in the cube, so diameter of the sphere is equal to the side of the cube. Hence ,the radius of the sphere is half of the length of the side.

If the length of side of the cibe = a , then radius of the sphere is \frac{a}{2}

Volume of the cube = a³, volume of the sphere = \frac{4}{3}π(radius)³ = \frac{4}{3}π(\frac{a}{2})³

volume of the cube outside the sphere = volume of the cube - volume of the sphere

=  a^3 - \frac{4}{3}π(\frac{a}{2})³

= a^3 -\frac{1}{6} \pi a^{3}

=a³(1 - \frac{\pi }{6})

Mice21 [21]

Answer:

Option A. 30\ pounds

Step-by-step explanation:

step 1

Find the volume of the sphere ( medicine ball)

The volume is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=10/2=5\ in ----> the radius is half the diameter

Convert inches to feet

Remember that

1 ft=12 in

r=5\ in=5/12\ ft

assume

\pi=3.14

substitute

V=\frac{4}{3}(3.14)(5/12)^{3}

V=0.3029\ ft^{3}

step 2

Find the weight of the ball

Multiply the volume in cubic foot by 100

0.3029*100=30.29\ pounds

Round to the nearest pound

30.29=30\ pounds

I'm confused on how to create ratios
Rzqust [24]

Answer:

Latoya:

cran : lem = 2 1/5 : 1 4/5

= 11/5 : 9/5

= 11 : 9

Lem : total = 9 : 20

Parker:

cran : lem = 2 1/2 : 3 1/2

= 5/2 : 7/2

= 5 : 7

Lem : total = 7 : 12
