A water balloon shaped like a sphere is filled with water. The water balloon has a diameter of 3 inches. Which measurement is cl
melisa1 [442]

Answer:

Option A. 14.13 cu. in

The volume of the water balloon is 14.13 in³

Step-by-step explanation:

First we calculate the radius

r = 3in / 2

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 1.5in

π = 3.14

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * 3.14 * (1.5in)³

V = 4.187 * 3.375 in³

V = 14.13 in³

The volume of the water balloon is 14.13 in³

Eddie's fishing. He has 1 1/4 ounces of weights on his line, but his bait isn't getting to the bottom of the lake. Eddie add ano
mario62 [17]
The initial weight is given by:
 1  \frac{1}{4}  = 1.25

 Then, we add a second weight:
 \frac{1}{2}  = 0.5

 Finally, we add a third weight:
 \frac{3}{4}  = 0.75

 Adding the three added weights, we can find the total weight.
 We have then:
 1.25 + 0.5 + 0.75 = 2.5

 The total weight is:
 2.5 = 2  \frac{1}{2} 

 Answer:
 
eddie now has 2  \frac{1}{2} ounces on his line

A. What is the difference in height between 30 m up a cliff and 87 m up a cliff? What is the distance between these positions?
Iteru [2.4K]

Answer:

A. 57m   B. 130m

Step-by-step explanation:

For problem A:

87m up a cliff - 30m up a cliff = 57m up a cliff

These are all positive values

For problem B:

100m above is talking about a positive value, making this a positive number

30m below is talking about a negative value, making this number -30

0 meters represents the surface

As you can see, this is forming a number line as of which

below the surface------------------------0m-------------------------above the surface

by substitution,

-30-----------------------------------------------0-------------------------------100

therefore, 100 - -30 = 130 meters
