Answer:
1995 => 22°
2005 => 36°
Step-by-step explanation:
Central angle of the sector representing nuclear energy in 1995 = percentage of nuclear energy in 1995 ÷ 100 × 360°
Nuclear energy is approximately 6% (rounded to whole number) in 1995.
Central angle =
Central angle representing nuclear energy in 1995 ≈ 22° (nearest whole number).
Central angle of the sector representing nuclear energy in 2005 = percentage of nuclear energy in 2005 ÷ 100 × 360°
Nuclear energy is approximately 10% (rounded to whole number) in 1995.
Central angle =
Central angle representing nuclear energy in 2005 = 36°.
