Answer:
this is the graph for y= -3x+8
Step-by-step explanation:
Answer:
- diameter: 16 cm
- circumference: 16π cm ≈ 50.27 cm
Step-by-step explanation:
The diameter is twice the radius:
d = 2r = 2(8 cm)
d = 16 cm
The diameter is 16 cm.
__
The circumference is pi times the diameter.
C = πd
C = π(16 cm)
C = 16π cm ≈ 50.27 cm
The circumference is 16π cm, about 50.27 cm.
Answer:
-2
<em>*Remember- negative ×/÷ positive= negative. Negative ×/÷ negative=positive</em>.
Explanation:
22÷ -11 (The parenthesis arn't really necessary)
- Okay, so you are going to ignore the negative and pretend they are both positive.
- Divide like normal- how many times does 11 go into 22? 11×2=22. 2 is your answer.
- Now, is it negative or positive? Look back at the * above. Looking at that, what's your answer? Well, you divided 22 by -11. Negative ÷ positive= negative. Therefore, your answer is -2

Volume generated by the areas R2 + R3 around the line OC
= (1/3) pi 1^2 * 3 = pi sq units
Volume generated by area R2 around OC is found as follows
the equation of the curve can be written as x = y^4 / 81
Integral between limits y = 0 and 3 of the curve is
pi INT x^2 dy = INT pi y^8 / 81^2 dx
= pi [3^9 / 9*81^2]
= pi/3
So the volume generated by R3 about OC = pi - pi/3 = 2pi/3
