Answer:
SA = 615.4 yd²
Step-by-step explanation:
The surface area (SA) of a sphere is calculated as
SA = 4πr² ← r is the radius
Here diameter = 14, thus r = 14 ÷ 2 = 7, then
SA = 4π × 7² = 4π × 49 = 196π = 196 × 3.14 ≈ 615.4 yd²
100% = 1
Because:to have 100 percent of something, you must have one whole. One whole equals 100% and the same backwards. I hope this helps!
So, the correct answer is equals =
C must be 80° to make the triangle angles add to 180°. The corresponding angles of similar triangles are congruent. So
Answer: y=80°
