Answer:

31.5 ft

Step-by-step explanation:

The length of the arc is the product of the radius of the circle, 11 ft, and the angle measure in radians. Arc PS has radian measure ...

(180° -16°)/180°×π = 41π/45

So, the length of arc PS is ...

s = rθ

s = (11 ft)(41π/45) = 451π/45 ft

s ≈ 31.5 ft

Multiply or divide as indicated. <br><br> x 2 • x 5

WARRIOR [948]

Hi there!

${x}^{2} \times {x}^{5} = x {}^{2 + 5} = {x}^{7}$

We can also write is out entirely.
${x}^{2} = x \times x$
${x}^{5} = x \times x \times x \times x \times x$
${x}^{2} \times {x}^{5} = \\ (x \times x ) \times (x \times x \times x \times x \times x) = \\ x \times x \times x \times x \times x \times x \times x = \\ {x}^{7}$
