Last question of a really important test! I really need some help!
A hollow ball is made of rubber that is 1 centimeter thick. The ball has a radius of 5 centimeters at the outside surface.
What is the approximate volume of rubber used to make the ball?
Use 3.14 for pi.
255.4 cm³
Answer:
area: 24
lateral area: 36
total area: I am not sure.
volume: 24
Step-by-step explanation:
area: length times width
lateral area: (perimeter of base) times height
total area: I do not know, sorry.
volume: length times width times height.
Answer:
x=52
Step-by-step explanation:
One of the properties of parallelograms is that angle A = Angle C
5y-54 = 3x eq1
Another property of parallelograms is that angle A + angle B = 180 degrees
5y-54+2y-60 = 180
7y = 180+114 = 294
y = 42
Putting this value in eq1
3x = 5*42-54 = 210-54 = 156
x = 52
1.5x + 7 = 20.5
First subtract 7 from both sides
1.5x = 13.5
Then divide both sides by 1.5
x = 9
Let me know in comments if you have questions
Yes because when your multiply every thing together you’ll have 9/15 miles
