Spheres
Surface area =
4tr²
Answer:
So, the surface area of the sphere is 100π cm².
Step-by-step explanation:
To calculate the surface area of a sphere with a radius of 5 cm, you can use the formula:
Surface area = 4πr²
Where r is the radius of the sphere. In this case, r = 5 cm. Plugging in the value for r, we get:
Surface area = 4π(5 cm)²
Now, we can simply square the radius (5 cm) and multiply the result by 4π:
Surface area = 4π(25 cm²)
Surface area = 100π cm²
Therefore , the surface area of the sphere is 100π cm².
