Answer:
pi times 4
Step-by-step explanation:
Circumference: pi times diameter (pi)(d) or pi times 2 times the radius (pi)(2r)
Answer:
(x + 4) and (x + 1)
Step-by-step explanation:
x² + 5x + 4
Consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (+ 5)
The factors are 4 and 1 , since
4 × 1 = 4 and 4 + 1 = 5 , then
x² + 5x + 4 = (x + 4)(x + 1) ← in factored form

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality
follows that A lies on the line.
B: x=3, y=13, then from the equality
follows that B lies on the line.
C: x=8, y=2, then from the inequality
follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality
follows that D lies on the line.
Answer:
h= 
Step-by-step explanation:
v=(
(3.141593))(r2)(2r+h)
Step 1: Flip the equation.
1.047198hr2+2.094395r3=v
Step 2: Add -2.094395r^3 to both sides.
1.047198hr2=−2.094395r3+v
Step 3: Divide both sides by 1.047198r^2.
h=
