Did you figure it out?

Answer:  1,221 seeds


Answers may vary, depending on where in the process you round. Since the diameter of the strawberry is 54 mm, its radius is 27 mm. When we substitute those values into the equation, we find that the surface area of a cone with the same dimensions is 1,944π square millimeters. If we divide that by 5, we get 388.8π, or about 1,221. So, we can approximate that the strawberry has 1,221 seeds.













Did you figure it out?

Answer:  100 pieces

Solution:  There are 10 layers of onion, so we can think of that as 10 pieces. When Francis cuts the onion in half, that makes twice as many pieces: 10 × 2 = 20. When he cuts each half onion horizontally 4 times, he multiplies the number of pieces by 5: 20 × 5 = 100.
