emil is ordering a cheesecake for his mom's birthday dinner.

Question

the lemon meringue surprise is $34.95, has an 11.5 inch diameter and is 3 inches tall. the penultimate indulgence is $49.95, had a 9 inch diameter and is 6 inches tall. which cheesecake is cheaper by cubic inch?

Answer 1

Lemon pi(11.5/2)^2 x 3 = 311.6067 cubic inches

Divide cost by this volume $34.95/311.6067 = 0.112

Penultimate. pi(9/2)^2 × 6 = 381.703

Divide cost by this volume. $49.95/381.703 = 0.131

The Penultimate is more expensive! It must taste delicious though!
