<em>Answer:</em>
<em>The surface area of the sphere is 86,525,84 yd^2</em>
<em></em>
<em>Step-by-step explanation:</em>
<em>The surface area of a sphere is equal to :</em>
<em>SA = 4 π r^2</em>
<em />
<em><u>Step 1 :</u></em>
<em>We have to find the radius of the sphere</em>
<em>The circumference of a circle is equal to :</em>
<em />
<em>C = 2π r</em>
<em />
<em>So then we have ,</em>
<em>C = 521.24 yd</em>
<em />
<em>Now we have to substitute and solve for r</em>
<em>521.24 = 2 ( 3.14 )r</em>
<em>r = 521.24/ 6.28 = 83 yd</em>
<em />
<em><u>Step 2 :</u></em>
<em>We have to find the surface area of the sphere</em>
<em>so ,substitute the values</em>
<em>then you'll get</em>
<em>SA= 4( 3.14 ) ( 83^2 ) = </em><em><u>86,525.84 yd^2</u></em>
<em><u /></em>
<em>This will be your answer : 86,525.84 yd^2</em>
