Week 3 (Maths): Pi
Pi Pi is defined as the ratio circumference, it's important for navigation. Pi is really important for rendering shapes, accurately involving circles Pi is approximated to 3.13159. Task For a task we needed to do, we looked at a circle which had a Circumference (C) of 314,159 miles. We needed to figure out the; Diameter (D), Radius (R), Area (A), Surface Area (S) & Volume (V). The formulas consisted of; C = Pi x D D = C/Pi R = C/2 x Pi S = 4 x Pi x R ² V = (4/3) x Pi x R ³ Diameter To work out the diameter it was 314159 (circumference)/ Pi = 99,999.91553 Radius To work on the Radius of the circle, I did 314159 (circumference) /2 x Pi = 49,999.95777 Area To work out the radius I've done Pi x 49,999.95777(radius) ² = 785398367 Surface Area To work out the Surface Area I've done 4 x Pi x 49,999.95777 (radius) ² = 3.141587347x10^10 Volume To work out volume is was (4/3) x Pi x 49.999.95777³ = 50235974489x10^14
