Answer:
volume is 1570 cm³
mass is 12560 g
Step-by-step explanation:
1m = 100 cm
the volume is :
1/4 x x 6² x 100 - 1/4 x
x 4² x 100
= 900 - 400
{ v = 1/4
d²h }
= 500
= 500 x 3.14
= 1570 cm³
the mass of the pipe is:
1570 x 8 = 12560 grams
Answer:
y + 1 = - (x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁)
where m is the slope and (x₁, y₁) a point on the line
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 4, - 1) and (x₂, y₂ ) = (3, - 3)
m = =
= -
and (x₁, y₁ ) = (- 4, - 1), then
y - (- 1) = - ( x - (- 4) ) , that is
y + 1 = - (x + 4) ← equation of line
