Answer:
21 in/hr
Step-by-step explanation:
Distance of snow fall = 3ft
Time taken = 1hrs
Unknown:
Rate of snowfall = ?
Solution:
The rate of the snowfall is the same as the speed of the fall;
Rate of snowfall =
Convert the ft to inches;
1ft = 12inches
3ft = 3 x 12 = 36inches
Input the parameters and solve;
Rate of snowfall = = 36 x
= 21
in/hr
the surface area of the sphere is π/4 cm^3
<h3>How to determine the surface area</h3>It is important to know the formula for surface area and volume of a sphere
Surface area =
Volume =
First, let's determine the value of radius, r
The value for volume was given as 256/3π cm3.
Pi cancels out and we have cross multiply to get the radius
Make r the subject of the formula
r = 4
Let's substitute to find the surface area
Surface area =
Surface area = π/4
Surface area = π/4 cm^3
Thus, the surface area of the sphere is π/4 cm^3
