Answer:
D 36πa^6b^9
Step-by-step explanation:
Step 1. Write the formula for the volume of a sphere.
V = (4/3)πr³
Step 2. Replace r with the given radius. Since the given radius is an expression, remember to enclose it in parentheses and cube the entire expression.
V = (4/3)π(3a²b³)³
Step 3. Simplify the expression. Start by cubing each factor inside the parentheses.
V = (4/3)π ×(3)³(a²)³(b³)³
To raise an exponent to an exponent, multiply the exponents.
V = (4/3)π × 27a^6b^9
V = (4/3 × 27)πa^6b^9
V = 36πa^6b^9
Answer: D 36πa^6b^9
Rectangle prisms have 6 flat surfaces.
Step 1: Simplify both sides of the equation.
1460
=
78.72
x
Step 2: Flip the equation.
78.72
x
=
1460
Step 3: Divide both sides by 78.72.
78.72
x
78.72
=
1460
78.72
x= 18.546748
Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane. ... The lines intersect at infinitely many points.

Answer:
Step-by-step explanation:
sinD = opposite/hypotenuse = 12/15 = 4/5
cosD = adjacent/ hypotenuse = 9/15 = 3/5
sinE = opposite/hypotenuse = 9/15 = 3/5
cosE = adjacent/ hypotenuse = 12/15 = 4/5
