Answer:
The Top Left square is your answer, 64pia^12
Step-by-step explanation:
A = (pi)r^2
A= (pi)(8a^6)^2
A = (pi)64a^12
A = 64pia^12
Answer:
They both have no possible solution.
Step-by-step explanation:
Don't know how to explain, but it's 100% right
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>
At most it will have 1 x-intercept
15/100=0.15
60*0.15=9
60-9=$52 after discount
