Answer:
C. Reflect triangle J across the y-axis, then across the x-axis.
The answer to this problem is -108
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
<span>500 = 0.5 kw
0.5 * 8 * 7.5 = 30c</span>
