Writing Functions for Geometric Shapes

Here we'll practice writing functions by creating functions that calculate things like the surface-areas and volumes of different 2d and 3d shapes.

Notes and Code	Outcome
Sphere Write a function that calculates the surface area (A) of a sphere of radius (r). $A = 4 \pi r^2$	Show Notes ▼
Sphere Test the function by finding the surface area of a sphere with radius 5.	Code Show Notes ▼ Results. Show Notes ▼
Sphere function test (multiple values) Use your sphere function to find the surface areas of spheres with radii: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.	Code. Show Notes ▼ Results. Show Notes ▼
Sphere: Volume Write a function that calculates the volume (V) of a sphere of radius (r). $V = \frac{4}{3} \pi r^3$
Cylinder Write functions to find the surface area and volumes of cylinders.
Rectangular Prisms Write functions to find the surface area and volumes of rectangular prisms.
Triangles Challenge: Write a function to find the area of a triangle given three points. Write a function that draws a triangle (using Glowscript) given three points.
