First off, area is in square cm while distance is in cm. The radius of a nickel is 1.0605 cm, so using the famous formula pi x r2 for the area gives:
3.141593 x 1.06052 = 3.5332 cm2
Surface area of a sphere (the golfball) = 4*pi*radius2 square cm
The curved surface area is 904.78cm2
Surface area = 4*pi*142 = 784pi square cm
The curved surface area is 301.6cm2
Surface Area = 4*pi*r2 = 6566.9 sq cm
The answer is 36π or approximately 113.1 cm.
The curved surface area is 75.4cm2
The curved surface area is 904.78cm2
Surface area of a sphere (the golfball) = 4*pi*radius2 square cm
Volume does not, surface area does.
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
I did not. In any case, the answer is incorrect since the surface area cannot be 0.9 cm.
Surface area = 4*pi*32 = 36pi square cm
The curved surface area is 301.6cm2
Surface area = 4*pi*142 = 784pi square cm
Surface Area = 4*pi*r2 = 6566.9 sq cm
The surface area is 403.44cm2
