Answer: 3/5xr=t and 5/3xt=r
Step-by-step explanation:
<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>
Hey there!
Let's keep our goal in mind. We're looking fo a sum, which means a number plus a number, or the answer to that problem.
In order to simplify this, we need to use the distributive property which can be defined as:
a(b+c) = ab+ac
Now, we can use this forumula to express:
6(3+9) = 6(3) = 6(9) = 18 + 54 = 72
Hope this helps!
