Answer:

28.5 cm^2

Step-by-step explanation:

Area of a sector - Area of the Triangle

Θ = central angle

Formula for Area of a sector:

Θ/360 πr^2

Plug in numbers

90/360 π (10)^2 = 78.5 cm^2

Formula for Area of a triangle

1/2bh

Plug in numbers:

1/2 (10) (10) = 50 cm^2

Now subtract to find the area of the segment:

78.5 - 50 = 28.5 cm^2

Step-by-step explanation:

Area= h* (a+b/2)

    = 10 * (10+16/2)

    = 10 * (26/2)

    = 10 * 13 = 130 sq.feet

The amount he needs to pay = 130 * 5 = $ 650

Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

\frac{AB}{AP} = \frac{BC}{PQ}

Plug in the values

\frac{9}{AP} = \frac{10}{8}

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8
