Final answer:
The surface area of a sphere with a diameter of 14 cm is 196π cm^2.
Step-by-step explanation:
To find the surface area of a sphere with a diameter of 14 cm, we can use the formula:
Surface Area = 4πr^2
Where r is the radius, which is half the diameter.
In this case, the radius is 14 cm / 2 = 7 cm.
Plugging in the values:
Surface Area = 4π(7^2)
Surface Area = 4π(49)
Surface Area = 196π cm^2
Therefore, the surface area of the sphere is 196π cm^2.
