Q. Look at the picture of the bullet below!The surface area of the bullet is ... (in π )
Identify Shapes: Identify the shapes that make up the bullet. It looks like a cylinder with a hemisphere on top.
Calculate Cylinder Area: Calculate the surface area of the cylinder part. The formula is 2πrh. But we don't have the actual measurements, so let's just call the radius 'r' and the height 'h'. So it's 2πrh.
Calculate Hemisphere Area: Calculate the surface area of the hemisphere. The formula for the surface area of a sphere is 4πr2, but since we only have half of it, it's 2πr2.
Add Areas for Total: Add the surface area of the cylinder and the hemisphere to get the total surface area of the bullet. So, the total surface area is 2πrh+2πr2.
