Yeah, I gotta read the questions better.
Perimeter not area.
diagonal length = √((28 - 12)² + (24 - 10)²) = 21.26
P = 12 + 10 + 28 + 24 + 21.26 = 95.26 units
sphere surface area = 4πR²
R = √(379.94 / 4(3.14) = 5.5 in
D = 2R = 11 inch
Answer:
Step-by-step explanation:
18x² + 2 = 2 * 9x² + 2 *1
= 2*(9x² + 1)
A because the graph of a direct proportion crosses the origin.
