Hello!Unfortunately, I can not see the image you linked. Instead, I'm going to walk you through how to solve for the area of the surface.In the first place, to find the value of your radio. If you are given diameter, will have to split in 2. If you are given a circumference, use the circumference formula (pi x diameter or 2 x pi x radius) to find the radius.Second, use the formula for the area of the surface of a sphere, which is SA = 4 x pi x r^2. Connect the radio, the square, below, several of the radio to the square by 4 to find the area of the surface in terms of pi. If you are looking for to the nearest tenth, or not, in terms of pi, multiply the value you just found for pi.I hope this helps!! :)If there's anything else I can help you, please let me know!
