Factorize using the difference of squares identity.

a^6 - b^6 = \left(a^3\right)^2 - \left(b^3\right)^2 = \left(a^3 - b^3\right) \left(a^3 + b^3\right)

Then

a^6 - b^6 = 11 \cdot 5 = \boxed{55}

I need major help with #2 and #3. Those are main concerns. If #5 could be done as well I’d appreciate it. It’s on Circles
jekas [21]

Answer:

2. 40.83 or 13π

3. a) 6π/5

b)21.6π

Step-by-step explanation:

2. Use the proportion arc length over angle measure:

x/360 = 7.94/70

x = 360 * .113 = 40.83 or 13π in exact form

3. a) 24π/20 because circumference divided by the total number of slices which reduces to 6π/5

b) 360/20 = 18 degrees per slice, so 13 slices have an angle measure 234 degrees

Set up a proportion between the area of the full pizza over the angle measure and the area of the pizza (the unknown value being solved) and its angle measure

144π/360 = x/234

(234*144π)/360 = 21.6π
