Answer:

Part A:

The estimate of the length of the crust of each pizza is given as follows;

a) The estimate of the length of the crust of the pizza with radius, r = 32 cm is 198 cm

b) The estimate of the length of the crust of the pizza with radius, r = 12.7 cm is 76.2 cm

Part B:

a) The calculated length of the crust of the pizza with radius, r = 32 cm is approximately 201.06 cm

b) The calculated length of the crust of the pizza with radius, r = 12.7 cm is approximately 79.796 cm

Step-by-step explanation:

Part A:

The estimate of the length of the crust of each pizza is given as follows;

a) For the pizza with radius, r = 32 cm

Length of crust = Estimate of the circumference of the pizza 2 × 32 × 3 = 198 cm

b) For the pizza with radius, r = 12.7 cm

Length of crust = Estimate of the circumference of the pizza 2 × 12.7 × 3 = 76.2 cm

Part B:

The calculated length of the crust of each pizza is given as follows;

a) For the pizza with radius, r = 32 cm

Length of crust = The circumference of the pizza 2 × 32 × π ≈ 201.06 cm

b) For the pizza with radius, r = 12.7 cm

Length of crust = The circumference of the pizza 2 × 12.7 × π ≈ 79.796 cm
