Answers

  1. The radius of the sphere is 5.04 cm rounded to the nearest centimeter.

    What is Surface Area?

    Surface Area is the total area of the outer surface of a three-dimensional figure.
    A sphere is a geometrical object that is analogous to a circle, all the points of the sphere are at the same distance from the center of the sphere.
    The surface area of a sphere is 320 square centimeters.
    The radius of the sphere has to be determined,
    The surface area of the sphere is given by,
    A = 4 π r²
    Substituting the values of A in the formula,
    320 = 4 π r²
    320 = 4 * 22* r² / 7
    320 * 7 /( 4*22) =  r²
    r² = 2240/88
    r²  = 280/11
    r = 5.045 cm
    The radius of the sphere is 5.045 cm.
