1472.50/ 5 weeks = 294.50/ week
294.50/7.75 per hour = 38 hours per week
Area of circle = π · r²
9 π = π · r²
9 = r²
3 = r
Volume of sphere = (4/3)π · r³
= (4/3)π · (3)³
= 4π · 3²
= 4π · 9
= 36π
Answer: the volume of the sphere is 36π

Answer:
Step-by-step explanation:
9(6+x)
by the distributive property,
distributing the 9 to each term in the brackets,
we get,
9*6 + 9*x
So yes, #1 is true.
---------------------------------------------------------------
(x+8)9
again by the distributive property,
giving the 9 to each term in the brackets,
x*9 + 8*9
which is NOT the same as
x + (8*9)
so #2 is false.
Hope that helps.
