<span>So we want to know the volume V of the volleyball if we know the diameter d=8.15 inches and we need to round it to the nearest hundreth. The volume of a volleyball is V=(4/3)r^3*pi, and since 2 radius are equal to the diameter we need to get the radius, so 2r=D and r=D/2 or r=4.075 inches. Now we get the volume after inputting the numbers: V=283.303032 inches^3. Rounded to the nearest hundreth: V=283.30</span>

A bear can run up to 18.47 feet per second. How many feet could the bear run in 3.9 seconds? 720.33 feet 7,203.3 feet 72.033 fee

JulsSmile [24]

Answer:

72.033 ft

Step-by-step explanation:

To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.

$\frac{18.47}{1}=\frac{y}{3.9}$

Step 1: Switch sides

$\frac{y}{3.9}=\frac{18.47}{1}$

Step 2: Apply rule: $\frac{a}{1}=a$

$\frac{y}{3.9}=18.47$

Step 3: Multiply both sides by $3.9$

$\frac{3.9y}{3.9}=18.47\cdot \:3.9$

Step 4: Simplify

$y=72.033$

The bear can run 72.033 feet in 3.9 seconds
