<span>Diameter of the sphere = 8 cm.
Therefore, the radius of the sphere = 8/2 = 4 cm
Volume of the sphere = 4/3 * 22/7 * 3 * 3 * 3 cu. cm.
The sphere is beaten and drawn into a wire, the wire is cylinder of the diameter = 0.2 cm
Area of the base of the cylinder = pi * r2 = 22/7 * 0.2 * 0.2 sq. cm
volume of the wire = pi * r2 * I = 22/7 * 0.2 * 0.2 * 1
Therefore, 22/7 * 0.2 * 0.2 * I = 4/3 * 22/7 * 4 * 4 * 4
Therefore I = 4/3 * 22/7 * 4 * 4 * 4 * 7/22 * 1/0.04
I = 256/3 * 1/0.04
I = 2113 cm</span>
Answer:
-90 - (-144)
Step-by-step explanation:
Here you go!
Since we're depositing, you'll add the three numbers.
45 + 27 + 18 = $90
Cody deposits 90 dollars in total.
If you write checks, the numbers go down. So you'll add them, and then subtract that by the 90 dollars Cody deposits.
You'll end up with:
45 + 27 + 18 - (21 + 93)
This can simplify to..
90 - (21 + 93)
But wait! Let's add what's in the parenthesis!
93 + 21 = 144
90 - 144 = t
t = -54
Solving this equation will give you: -54
But the simple way is -90 - (-144)

Answer:
Hi there!
Your answer is:
It will take 2.2 months for both gyms to be the same amount of money!
Step-by-step explanation:
Fitness 19:
39+ 17x
Anytime Fitness:
50+ 12x
Put them equal to each other:
39+17x = 50+12x
-12x
39+5x = 50
-39
5x = 11
/5
x= 2.2 months
39+17(2.2)= 76.4$
50+12(2.2)= 76.4$
Hope this helps!
Mean of a set of numbers is the quotient when their sum is divided by the number of items in the set. For the given above, their sum (S) is,
S = 5.2 + 8.3 + 8.5 + 7.7 + 7.8 + y = 37.5 + y
The mean (m) is calculated through the formula,
m = S / n
where n is the number of items. In this given there are 6 items including y.
7.1 = (37.5 + y) / 6 ; y = 5.1
Therefore, y is equal to 5.1.
