Answer:

2,144.66 in³

Step-by-step explanation:

∵ The volume of a sphere,

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

Where,

r = radius of the sphere,

If Diameter of a sphere = 16 inches,

Then the radius of the sphere, r = \frac{16}{2} = 8 inches

So, the volume of the sphere,

V=\frac{4}{3}\pi (8)^3

=\frac{4}{3}\times 512

=2144.66058485

\approx 2144.66\text{ square inches }

∵ the  fishbowl shaped like a sphere having diameter 16 in is filled with water.

Thus, the volume of the water in the fish bowl = volume of sphere having diameter 16 inches

=  2,144.66 in³

Answer:

The volume of the water in the fishbowl is equal to

(682\frac{2}{3})\pi\ in^{3}  or  2,144.6\ in^{3}

Step-by-step explanation:

we know that

The volume of the sphere (a fishbowl) is equal to

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

In this problem we have

r=16/2=8\ in ----> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (8^{3})=\frac{2,048}{3}\pi\ in^{3}

convert to mixed number

\frac{2,048}{3}\pi\ in^{3}=\pi (\frac{2,046}{3}+\frac{2}{3})=(682\frac{2}{3})\pi\ in^{3}

(3.14156)*(682\frac{2}{3})=2,144.6\ in^{3}

Ralph and Waldo start in towns that are 70 miles apart and travel in opposite directions for 4 hours.
Lina20 [59]

Answer:

Step-by-step explanation:

Let Waldo's speed = W

Let Ralph's speed = W + 15

A

Waldo's distance = speed * Time

Time = 4 hours.

Speed = w

distance = 4 * w

B

Ralph's speed is W + 15. It's not clear if you need a number. We'll get around to that later.

C

Ralph traveled  4*(W + 15)

D

4w + 70 + 4(W + 15) = d

You really can't get a definite answer to these questions. Even if you knew whether they were heading away from each other or towards each other it wouldn't help.
