False Happy Thanksgiving :)
Theres no answer to this promblem do you wanna add more
In math and and other types of school stuff :) if that's what your asked
The ratio of the radii is 2:1, so the ratio of their surface areas is 4:1. <span>The area of a sphere is defined by 4 * pi * r^2 </span>
<span>So if the radius of the first sphere is 2r, then it would be (2r)^2 = 4r^2 </span>
<span>The rest is the same. So the ratio of their surface areas would be </span>
<span>4 * pi * 4r^2 divided by </span>
<span>4 * pi * r^2 </span>
<span>or 4.</span>
55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
