We just need to <u>plug in 7 for B! </u>
Let's do it !
2 + (10 - 7)
<em>We always start with the parenthesis first ! It's just a rule in math :) </em>
10 - 7 = ?
10 - 7 = 3
Now we have ...
2 + 3
2 + 3 = 5
Your final answer is 5!
I hope I helped :) Just comment if you have any questions and remember to vote me "brainliest" if you like my answer !!!
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>
