1) just multiply each dimension by 0.5
2) Huh? cylinders and spheres are already 3D
Anyway, by enlarging by a factor of 3, its area is enlarged by a factor of 3^2 = 9.
Its current area is 2π*5*10 + 4π*5^2, so just multiply that by 9.
Chef Potato's body has a cylinder in the middle and two half spheres that make up his bottom and head. He has the two dimensional shape measurements as follows: 20 cm in total length, 5 cm between the end of the cylinder and the top of the top sphere. Reduce Chef
1.) Potato by a scale factor of 0.5.
2.) Chef Potato needs to be converted from a two dimensional shape to a three dimensional object and then enlarged to 300% of his original size. The three dimensional chef potato is similar in shape to a capsule made of a half sphere at the top, and a half sphere at the bottom and a cylinder in between. Determine the surface area of the enlarged three dimensional chef potato and the scale factor.
