Question

what is the surface area of the solid? 10 2,628 units squared 914 units squared 1,256 units squared

Explanation:

Step1: Identify the solid and formula

The solid is a sphere. The formula for the surface area of a sphere is \( SA = 4\pi r^2 \), where \( r \) is the radius. From the diagram, the radius \( r = 10 \).

Step2: Substitute the radius into the formula

Substitute \( r = 10 \) into \( SA = 4\pi r^2 \). So, \( SA = 4 \times \pi \times 10^2 \).

Step3: Calculate the value

First, calculate \( 10^2 = 100 \). Then, \( 4 \times \pi \times 100 = 400\pi \). Using \( \pi \approx 3.14 \), we get \( 400 \times 3.14 = 1256 \).

Answer:

1,256 units squared
