Answer:
Step-by-step explanation:
"A" must be added to first expression to get the second one:
- A + 2x² - 3 xy + 5yz = x² - xy + y²
- A = ?
------------------------
- A = x² - xy + y² - (2x² - 3 xy + 5yz) =
- x² - xy + y² - 2x² + 3 xy - 5yz=
- -x² + y² + 2xy - 5yz
Step-by-step explanation:
Q1. diameter =90yd radius=45
circumference of circle=2×pi×radius
"" =2×3.14×45
=282.6 yd
Q2 diameter =18m radius=9
area of circle=pi×(radius)
""" =3.14×9²
""" =254.34m²
A force acting on an object may cause the object to change shape, to start moving, to stop moving, to accelerate or decelerate.
When two objects interact with each other they exert a force on each other, the forces are equal in size but opposite in direction.
The formula for the volume of a cylinder is
V=πr²*h where r=radius and h=height
plug in the data we know
V=π8²*2
V=π*64*2
V=128π
V=402.1cm³
Answer=402.1cm³
