Formulas: The formulas for the surface area (SA) and volume (V) of a sphere are: Surface Area (SA) = 4r Volume (V) = (4/3)r where: (pi) is a mathematical constant approximately equal to 3.14 r is the radius of the sphere Calculations: Find the radius (r): If you measured the diameter (d), then r = d / 2. Substitute the radius (r) you obtained into the formulas for surface area (SA) and volume (V). Example (assuming measurements from your picture): Let's say the picture you took shows a diameter of 10 cm. Radius (r) = d / 2 = 10 cm / 2 = 5 cm Surface Area (SA): SA = 4 * (5 cm) SA 314.16 cm (rounded to two decimal places) Volume (V): V = (4/3) * (5 cm) V 523.59 cm (rounded to two decimal places) Answer for the Scavenger Hunt: a) Dimensions: Diameter (d) = __________ (replace with your measurement) b) Formulas: Surface Area (SA) = 4r Volume (V) = (4/3)r c) Surface Area: SA = __________ (replace with your calculated value) d) Volume: V = __________ (replace with your calculated value)
