Answer:
144*pi cm^2
Step-by-step explanation:
The formula for the surface area of a sphere is A = 4*pi*r^2.
If the diameter is 12 cm, the radius, r, is 6 cm.
Thus, in this case, the surface area of the sphere is
A = 4*pi*(6 cm)^2 = 144*pi cm^2.
Answer:
Surface area = 452 square cm.
Step-by-step explanation:
surface area of a sphere with a diameter 12 cm
Diameter = 12 cm
Radius = diameter divide by 2= [tex]\frac{12}{2} =6[/tex]
Surface area of a sphere = [tex]4\pi r^2[/tex]
Where 'r' represents the radius of the sphere
[tex]4\cdot \pi \cdot 6 \cdot 6= 452.3893421[/tex]
Now round the answer to nearest whole number
Surface area = 452 square cm.
