2) The intensity of radiation (R), measured in Rems, of a radioactive particle varies inversely as the square of the distance (d), measured in feet, from the particle. For a particular particle, the relationship is described by
625
the function R(d)=
da
a) At a distance of 10 feet, what is the intensity of the radiation, in Rems?

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.
