Answer:
5.1 cm² approximately
Step-by-step explanation:
A lighter= Area inscribed -1/2r² sin80°
A lighter=π r² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=π(5cm)² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=3.14*25cm²(80°/360°) - 12.5cm² sin 80°
A lighter=17.444…cm² - 12.31009... cm²
A lighter=5.13cm² approximately
Answer:8pts
Step-by-step explanation:
<span>We know that the surface of a sphere is: S = 4 * pi * r^2
The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51
And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32
So the surface of Jupiter is around 11^2 times bigger than the Earth</span>

Step-by-step explanation:
100-55=45
45% of 187
187*45=8415
8415/100=84.15
84.15 is 45% of 187
