Respuesta :
The area of a sphere is : 4π.R²
Here R(radius) = 10 ===R²=100
& The Area is 400π inches²
Here R(radius) = 10 ===R²=100
& The Area is 400π inches²
Answer: A. [tex]400\pi\text{ square inches}[/tex]
Step-by-step explanation:
Given: The radius of the sphere = 10 in.
The formula to calculate the surface area of the sphere is given by:-
[tex]\text{Surface Area}=4\pi r^2[/tex], where r is the radius of the sphere.
For r=10 in. we have
[tex]\text{Surface Area of sphere}=4\pi (10)^2\\\\\Rightarrow\text{Surface Area of sphere}=4\pi(100)\\\\\Rightarrow\text{Surface Area of sphere}=400\pi\text{ square inches}[/tex]
