Step-by-step explanation:
Answer: 594336
Step-by-step explanation: Because of google
<span>given:
bull's eye radius= x
width of surrounding rings=y
solution:
Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring
=Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
=Ď€(2xy+7y^2)
hence the area of the outermost ring in terms of x and y is π(2xy+7y^2).</span>
To solve for x, put all of the angle measurements on one side of an equation and set it equal to 360, because the sum of any exterior angles is 360 degrees. hope this helped!
