1+4 =5 2+5=12 3+6=21 8+11=

Answers

1 + 4 = 5
2 + 5 + 5 = 12
3 + 6 + 12 = 21
8 + 11 + 21 = 40
So the missing number is 40 and that we can see from the above deduction. Actually the number that we get from the previous addition is added with the next addition to get the result. This is the link between the equations.

It would be 40 because it adds the sum of the equation before it

There are many cylinders with a height of 9inches. Let r represent the radius in inches and v represent the volume in cubic inches what belongs in cell A

Answers

Complete question :

There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches.

a. Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of , or round to the nearest cubic inch.

Answer:

A = 9π in³

B = 36π in³

C = 81π in³

Step-by-step explanation:

Radius, r = 1, 2, 3

Height of cylinder = 9

Volume, V of cylinder : πr²h

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³
