Find the volume of the sphere shown give each answer rounded to the nearest cubic unit

4,189 mm^3

Step-by-step explanation:

Use the volume of the sphere formula:

V = 4 /3πr^3

Substitute 10 into r.

V = 4 /3π(10)^3

Multiply.

V = 4/3π1000

Insert 4/3π1000 in your calculator.

V = 4188.790205

Now round the answer to the nearest cubic unit.

V = 4189

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
