Answer:
b) It has a value less than 2
Step-by-step explanation:
Divide both sides of the inequality by 12 to get
t < 2 so the answer is b)
1 4/5 would be the answer
Answer:28
Step-by-step explanation:
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>
