Answer:
Step-by-step explanation:
volume of a cylinder=πr^2h
=3.14*2^2*4
=3.14*4*4
=50.24 m^3
Equation is :
( x + 2 )² + ( y - 1 )² = r²
( - 4 + 2 )² + ( 1 - 1 )² = r²
4 = r², than we will plug in to a formula:
( x + 2 )² + ( y - 1 )² = 4
x² + 4 x + 4 + y² - 2 y +1 = 4
x² + y² + 4 x - 2 y + 1 = 0
Answer: B )
