A = 81 square in.
s = sqrt(A)
s = sqrt(81)
s = 9 in.
The volume of a sphere is
V_s = 4/3 * pi * r_s^3
The volume of a cone is
V_c = 1/3 * pi * h * r_c^2
Since we know that the two volumes are equal, we can say
V_s = V_c
4/3 * pi * r_s^3 = 1/3 * pi * h * r_c^2
Let us now isolate r_c, the radius of the cone:
4/3*r_s^3 = 1/3 *h*r_c^2
sqrt((4*r_s^3)/h) =r_c = 12 cm
So the radius of the cone is 12 cm
Answer:
64
Step-by-step explanation:
step one would be to divide 140 by 56 and once you do that you would get 2.5 so then you would divide 160 by 2.5 to get 64.
-6+-7 is the correct answer
