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

Answer:

The exact answer in terms of radicals is x = 5*\sqrt[3]{25}

The approximate answer is x \approx 14.62009 (accurate to 5 decimal places)

===============================================

Work Shown:

Let y = \sqrt[5]{x^3}

So the equation reduces to  -7  = 8-3y

Let's solve for y

-7 = 8-3y

8-3y = -7

-3y = -7-8 ... subtract 8 from both sides

-3y = -15

y = -15/(-3) ... divide both sides by -3

y = 5

-----------

Since y = \sqrt[5]{x^3} and y = 5, this means we can equate the two expressions and solve for x

y = 5

\sqrt[5]{x^3} = 5

x^3 = 5^5 Raise both sides to the 5th power

x^3 = 3125

x = \sqrt[3]{3125} Apply cube root to both sides

x = \sqrt[3]{125*25}

x = \sqrt[3]{125}*\sqrt[3]{25}

x = \sqrt[3]{5^3}*\sqrt[3]{25}

x = 5*\sqrt[3]{25}

x \approx 14.62009

1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m

2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft

3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
