Surface area of Sphere = 4πr²
* The bowl, is half a sphere (hemisphere)
Inside radius, r = 6 cm
inside hemisphere surface area = (1/2)4π(6)²
= 2π36
= 72π
= 226.2 cm²
-----------------------------------------------
Outside hemisphere surface area = (1/2)4π(6.5)²
= 2π(42.25)
= 84.5π
= 265.5 cm²
--------------------------------------------
Volume of Sphere = (4/3) πr³
1/2 of this fills the bowl, hemisphere
inside Hemisphere volume = (1/2)(4/3)π(6)³
= (2/3)π(216)
= 144π
= 452.4 cm³
