Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) is
As = 4×pi×r²
our radius r (half of the diameter) here is 5m.
As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²

Answer:
a. 16
Step-by-step explanation:
Triangles = 180 degrees
180 - 80 = 100
100 = (4x - 4) + (0.5x + 32)
4x - 4 + 0.5x + 32 =100
(4x + 0.5x) +(-4 + 32) = 100
4.5x + 28 = 100
4.5x + 28 -28 = 100 - 28
4.5x = 72
4.5x/4.5 = 72/4.5
x = 16
