T he area of a circle is pr 2. Define r as 5, then find the area of a circle, using MATLAB®.(b) The surface area of a sphere is 4pr 2. Find the surface area of a spherewith a radius of 10 ft.(c) The volume of a sphere is 4/3pr 3. Find the volume of a sphere with aradius of 2 ft.

Area of Circle = 78.5398

Surface Area of Sphere =  1.2566 x 10^3 = 1256.6 ft

Volume of Sphere =  33.5103 ft

Explanation:

Please find below the written MatLab script used to solve the problem. I had to define r in each case to solve for the Area of the circle, the surface area and the volume of the Sphere.

r=5; % define r as 5

a=pi*r^2;% calculate the area of the circle

AreaOfCircle=a

r=10; % define r and 10 ft

sa=4*pi*r^2; %Calculate the surface area of the sphere

SphereSurfaceArea=sa

r=2;% define r as 2 ft

vs=(4/3)*pi*r^3;% Calculate the volume of the sphere

VolumeShere=vs
