Question

What is the total cost of a jar of jelly with a radius of 3 cm and a height of 10 cm if the cost is 0.04 cents per cm³? Use 3.14 for π. (Round to the nearest hundredth). 11.30 37.68 3.60 12.00

Answer 1

Answer: 11.30

Explanation:

We wouod solve this using the formula:

= πr²h

= 3.14 × 3² × 10

= 3.14 × 9 × 10

= 282.6cm³

Since the cost is 0.04 cents per cm³, the total cost will then be:

= 282.6 × 0.04 cents

= 11.30 cents
