Answer:
exact: 48pi cm^2
approximate: 150.8 cm^2
Step-by-step explanation:
SA = 2 * (pi)r^2 + 2(pi)rh
SA = 2 * pi * (3 cm)^2 + 2(pi) * 3 cm * 5 cm
SA = pi(18 cm^2 + 30 cm^2)
SA = 48pi cm^2
SA = 150.8 cm^2
x=3
5(2x-3)=15
10x-15=15
10x=30
34.88 feet
SAS
The triangles are compared with 2 sides and 1 angle. So, it is SAS
C(n) = 12 + 1.5(n – 1)
The answer is 6800 = 80m
