We know

$\boxed{\sf cos\Theta=\dfrac{b}{h}}$

$\\ \sf\longmapsto cos22=\dfrac{x}{47}$

$\\ \sf\longmapsto 0.9=\dfrac{x}{47}$

$\\ \sf\longmapsto x=47(0.9)$

$\\ \sf\longmapsto x=42.3$

Fond the area of the shaded sector of circle C to the nearest tenth

Lesechka [4]

Solution

Step 1

Write an expression for the area of sector

$Area\text{ (A) = }\frac{\theta}{360}\times\pi\times r^2$

Where

θ = 52°

π = 3.14

r = 8cm

Step 2

Find the area of the sector after substitution of values into the formula above.

$\begin{gathered} A\text{ =}\frac{52}{360}\times3.14\times8^2 \\ A=29.028cm^2 \end{gathered}$

To the nearest tenth the area of the shaded sector of circle C = 29.0cm²
