Answer:
22 degrees, 1. 2 degrees, 2. 14 degrees, 3. 14 degrees, 4.30 degrees
Step-by-step explanation:
<u><em>10 2/7 ÷ 3/14</em></u> First Write The Equation
<u><em>72/7 ÷ 3/14</em></u> Use KCF which is Keep, Change, and Flip
<u><em>1008/21</em></u> Use Division Of Equality
<u><em>Answer: 48</em></u>
<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>
