Answer:
1557/1892
Step-by-step explanation:
Your calculator can do this:
To find area you
Multiply base times height.
Bh=A
So multiply the base times the height of the graph?
So 6 times 6 equals area.
Of course since we are dealing with the 4 quadratics 6 can be negatives or positive.
Whether it’s negative or not area is area.
If you’re finding the coordinates shapes area, sorry I have no idea
I am doing this too but mines definitely different
NO the answer would be -1 not -10
Answer:Yes it doubles
Step-by-step explanation:v=πr^2h is the formula to find the volume of a cylinder. V=π5^2•10 will equal 785.4. increasing the radius by 5 will double it. V=π^10•10 equals to 3141.59
