Question

I need help with this practice problem Having trouble solving it completely

Answer 1

The area of sector formula is :

`A=(1)/(2)r^2\theta`

where r = radius

θ = central angle in radians

From the problem, we have :

r = 7 inches

θ = 4π/15

Using the formula above :

`\begin{gathered} A=(1)/(2)(7)^2*(4\pi)/(15) \\ A=(98\pi)/(15) \end{gathered}`

ANSWER :

The area of the sector is 98π
