Someone pls help me ill give out brainliest pls don’t answer if you don’t know
iren [92.7K]

Answer:

Step-by-step explanation:

The area of a sector has the formula

A_s=\frac{\theta}{360}*\pi r^2 Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:

A_s=\frac{75}{360}*(3.14)(4)^2 and simplifying that a bit to look less threatening, but not by much:

A_s=\frac{5}{24}(3.14)(16) and

A_s=\frac{251.2}{24}=\frac{157}{15}=10.466666666... Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
