Answer:
Surface area = 452,4
Step-by-step explanation:
radius = 6 cm
Surface area = 4πr²
Surface area = 4(3.1416)(6)²
Surface area = 12.5664 (36)
Surface area = 452, 3904
Surface area = 452,4
Answer:
452.3893421 cm^2
452.4 (to one decimal place)
Step-by-step explanation:
Radius (r) - 6cm
The surface area of sphere = 4pi r^2
therefore:
4 * pi * 6^2
4 * pi * 36
144 * pi
452.3893421 cm^2
452.4 (to one decimal place)
