Answer:
3.6000
Step-by-step explanation:
I did this three different ways I think this is right.
Good idea to look up the formula for "surface area of a sphere" and to write it down for later reference. It is A=4 pi r^2, where r is the radius of the sphere.
If the given sphere has a diameter of 7 cm, what is the radius of this sphere?
Write your answer inside the parentheses, below:
Sphere surface area = 4 pi (r)^2, or (in this case), A = 4(3.14)( )^2
Answer:
89.10 / 4.95 is 18. so the first one is 18.
6 and 9, so we have to find the LCM. 6,12,18 and 9,18, so the first one to get a red and blue cap is the 18th bottle.
We know that the 18th bottle will get a red and blue, so then we have to find the LCM of 18 and 10. 18,36,54,72,90 10,20,30,40,50,60,70,80,90.
The first one to get all three is the 90th bottle.
Hope this helps plz hit the crown :D
Answer:
ok so u have to -the 12
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
The central angle is 100/360 or 5/18 of the full circle. This means that the length of the minor arc it forms is also 5/18 of the full circumference. We can set up an equation to represent this. (Let circumference = C.) The equation will be 25 = 5/18 * C, and when we solve for C, we get C = 90. Now, let's find the radius!
The circumference formula of a circle is C = 2πr, where r is the radius and C is the circumference. We are solving for r. We know that C = 90, and we can use 3.14 for π. When we plug these values in, we get 90 = 2 * 3.14 * r. When we simplify the right side, we get 90 = 6.28 r, and when we solve for r, we get r≈14. Hope this helps!
