Ceres has a shape, about 975 x 925 kilometers across. Use the average of these two measurements for its diameter, and halve this to get the radius.

Ceres has a shape, about 975 x 925 kilometers across. Use the average of these two measurements for its diameter, and halve this to get the radius. This must be multiplied by 1,000 to convert into meters, and then again by 100 to convert it into centimeters.
radius of Ceres: r =____________ x10_ meters, or ______x10_ centimeters.
