The sphere shown has a diameter of 36 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.
the surface area of this sphere is 4,069.44
you might need to round this answer up
Answer:
Surface area of the sphere = \(4069.44 in^2\)
Step-by-step explanation:
Given is a sphere which has diameter of 36 inches.
Let us find radius of the sphere.
Radius of the sphere = \(\frac{36}{2} =18 inches\)
Surface area of the sphere = \(4\pi r^2\)
Substitute the value of r in the formula to get
\(SA = 4(3.14)(18^2)\\\)
\(=4069.44 in^2\)
Surface area of the sphere = \(4069.44 in^2\)
