FORMULA FOR SURFACE AREA OF SPHERE = 4 pi r^2
<span>r = 6 " area = 4 pi X 6 X 6 = 144 pi " squared </span>
<span>r = 12 " </span>
<span>area = 4 X pi X 12 X 12 = 576 pi" squared </span>
<span>ANSWER Area will be 4 times the original</span>
Answer:
We use the formula:
S 10 = 8 · [(1/2)^9 - 1] / (1/2 - 1 );
Then, S 10 = 8 · ( 1/512 - 1 ) / ( 1/2 - 1 );
S 10 = 8 · ( - 511 / 512 ) / (-1 / 2 );
S 10 = ( - 511 / 64 ) · ( - 2 );
S 10 = + 511 / 32;
S 10 = 15.96;
