Respuesta :
area of circle = pi x r^2
using 3.14 for pi
area = 3.14 x 15^2 = 706.5 square miles
270/360 = 0.75
706.5 * 0.75 = 529.875
rounded to nearest mile = 530 miles
Answer:
Step-by-step explanation:
Alright, lets get started.
The light house light is making an arc, so please refer the diagram I have attached.
The angle is 270 degree. Converting it into radians :
[tex]270*\frac{\pi }{180} = 4.7124[/tex]
The radius of the arc will be = 15 m
So, area of the arc will be = [tex]\frac{1}{2}*angle*radius^2[/tex]
So, area of the arc will be = [tex]\frac{1}{2}*4.7124*15^2[/tex]
So, area of the arc [tex]= 530.143[/tex]
To the nearest square meter, the area id 530 square meters. : Answer
Hope it will help :)
