Answer:

Step-by-step explanation:

a) U -----> union

Union of two sets is the set of all distinct elements that are in A or B

A U B = {8 , 14 , 17 , 16, 9 , 15}

∩ ----------> intersection

Intersection of two sets is the set of all distinct elements that are in both A and B

A ∩ B = {14,17}

b) A' = {9 , 15 , 16 , 10 , 11 , 12 , 13}

P(A') = 7/10

Find the volume of a sphere with a diameter of 22m. Round to the nearest tenth.

irinina [24]

$\text{The formula of the volume of a sphere:}\\\\V=\dfrac{4}{3}\pi r^3$

$\text{We have:}\\2r=22m\to r=11m$

$\text{substitute}\\\\V=\dfrac{4}{3}\pi\cdot11^3=\dfrac{4}{3}\pi\cdot1331=\dfrac{5324}{3}\pi\approx5572.5\ m^3$
