Answer:

Step-by-step explanation:

CONE:

height of cone = h =  12 cm

r =3.5 cm

Volume \ of \ cone =\dfrac{1}{3}\pi r^{2}h

                           =\dfrac{1}{3}*\dfrac{22}{7}*3.5*3.5*12\\\\\\=22*0.5*3.5*4\\\\= 154 \ cm^{3}

Cylinder:

h = 16 cm

r = 3.5 cm

Volume \ of \ cylinder = \pi r^{2}h\\

                                = \dfrac{22}{7}*3.5*3.5*16\\\\\\= 22*0.5*3.5*16\\\\= 616 \ cm^{3}

Total volume = 154 + 616

                       = 770 cm³

Use the equation y= -x + 5 <br> •What is the y-intercept<br><br> •What is the slope of this line
Rudik [331]
Y = mx + b is the format for this equation, where <em>m</em> is the slope and <em>b</em> is the y-intercept. with that information, (-1) would be your slope, taking the assumed coefficient of 1 from the x, and the y-intercept is 5.
