Answer: 201.06 in²
Step-by-step explanation:
Use the equation πr² to find out the area of a circle.
Since the diameter is 16 the radius is half of that, 8.
π(8)²
Work out that equation and you're done!
Answer:
x = - 8, y = 2
exact: 48pi cm^2
approximate: 150.8 cm^2
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
6x + 13 = 37
6x = 37 - 13
6x = 24
x = 24/6
x = 4
Answer: x = 4
