Answer 1

Answer:

B)  82.43 in³ (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a sector of a circle}=\left(\dfrac{\theta}{360^{\circ}}\right) \pi r^2$

Given:

• diameter = 30 ft ⇒ radius = 15 ft
• $\theta$ = 42°
• $\pi$ = 3.14

Substituting the given values into the equation:

$\implies \textsf{Area}=\left(\dfrac{42^{\circ}}{360^{\circ}}\right)(3.14)(15)^2$

$\implies \textsf{Area}=82.425$

⇒ Area = 82.43 in³ (nearest hundredth)

Answer 2

• radius=r=30/2=15ft

So

Area of sector we need

• Ø/360×πr²
• 42/360×π(15)³
• 7/60×π(225)
• 82.43ft²
