Answer:
Volume of the sphere is 
Step-by-step explanation:
It is given diameter of the sphere d = 6 cm = 0.06 m
Radius of the sphere

We know that volume of the sphere is given by

Therefore ,


Therefore volume of the sphere is 
80 40 20 10 5
Step-by-step explanation: Divide 20 by 40 then 40 by 80 They all are divisible by .5so then times .5 to get the next terms
Answer:
x²y²+xy²+3+xy+2y²
Step-by-step explanation:
(2x²y²+x²y+xy²+3)-(x²y²+x²y²+x²y-xy-2y²)
1. remove the parentheses (when there’s - in front of an expression in parentheses change the sign of each term of the expression)
2x²y² + x²y + xy² + 3-x²y² - x²y² - x²y + xy - 2y²
2. eliminate the opposites
2x²y² + xy² + 3 -x²y² + xy +2y²
3. collect like terms
x²y² + xy² + 3 + xy + 2y²
Answer:
A = $ 262.81
Step-by-step explanation:
The perimeter is the distance all the way around.
That's the sum of all the sides.
A triangle has 3 sides.
In an equilateral triangle, they're all the same length.
If one of them is 9.9 cm, then all of them add up to (3) · (9.9 cm) .
