Question

1. BC = 16 ft2. PQ = 22 cm139RS1с3. JK = 3 mm4. GH = 13 ydGK126845. YZ = 9 in6. EF = 28 mEF11542ZCG

Answer 1

Let's begin by listing out the given information:

The area of a sector is calculated using the formula:

1.

`\begin{gathered} Area=(\theta)/(360^(\circ))*\pi r^2 \\ \theta=51^(\circ) \\ r=BC=16ft \\ \pi=3.14 \\ Area=(51^(\circ))/(360^(\circ))*3.14*16^2 \\ Area=113.88\approx114 \\ Area=114ft^2 \end{gathered}`
