Please help with Part A and Part B

1 answer:

5 0

Part A:
The area of the rectangle will be the length times the width, so 4•(x+3). Using distributive property, you'll multiply every term inside the parentheses by 4.

The area of the rectangle can be expressed by 4x+12.

Part B:
Multiply 4•2 and (x+3)•2, then multiply them together.

8(2x+6) Now use distributive property to find your answer simplified.

16x+48 is your answer

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800

Alenkinab [10]

For this case we can model the problem as a cylinder.
The volume of a cylinder is given by:
$V = Ab * h
$
Where,
Ab: base area
h: cylinder height
Substituting values in the equation we have:
$800 = Ab * 46
$
From here, we can clear the area of the base
Answer:
An equation that can be used to find the area of the circular base is:
$800 = Ab * 46$
