Area of a circle is πr².
Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>
Surface area of a sphere is 4πr².
4<span>π(3.017)</span>² = 114.4 to 1DP
Option B
Mark BRAINLIEST if you are satisfied with the answer.
The range is {y E R: y < or = 0}
{–4, 1} I'm pretty sure!!
