no one can answer this because this is like a project worksheet.

we can’t measure what ever the math project is about so I could explain a few things

Step-by-step explanation:

For B:

you would put the circular object your project is about

For C:

you would need to measure your circular thing all the way across it in the centimete side of a ruler and you would find your answer.

For D:

you need to find the area of your circle and make an expression. Like let’s say the area of your circular object was 4, your expression would be 2+2=4

For E:

Find the area of your circular object and multiply it by 3.14
