You are going to solve this in such a quick, slick way
that you will blink and not believe it. Fasten your seat belt.
Here are the tools you'll need:
-- Volume of a cylinder = (pi) (radius)² (height)
-- Volume of a sphere = (4/3) (pi) (radius)³
Now ... the question says that your cylinder and your sphere
have the same volume. Fine ! So you can immediately write
an equation saying that their volumes are equal.
(pi) (radius)² (height) = (4/3) (pi) (radius)³
Divide each side by pi: (radius)² (height) = (4/3) (radius)³
Divide each side by (radius)² (height) = (4/3) (radius)
Fill in the given height: (6 cm) = (4/3) (radius)
Multiply each side by 3/4 : (6 cm) x (3/4) = radius
I'm pretty sure that you can take over now and find the radius.
Answer:
To calculate the circumference, you need the radius of the circle: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the circle.

Answer:
Prime numbers
Step-by-step explanation:
Consider that a prime number is a number with only two factors: 1 and itself (Example: {2, 3, 5, 7, ...}). Also, state that 2 is the only even prime number.
The set of all even numbers within the set of prime numbers can be described as {2}. Therefore, the universal set is all prime numbers itself.
(x+15)+(x-13)=180
2x+2=180
2x=178
x=89
∠B=x-13=89-13=76°
Hope my answer helped u :)
