Use a fives fact to help you solve 7x6.

42

Step-by-step explanation:

Since 7x5=35, then 7x6=42. This is known as the fives fact rule, and I used it to figure it out.

Hope this helps! :)

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
