To find the center of the circle, set the x-component equal to zero and the y-component equal to zero to find the ordered pair.

x+1=0
x=-1

y+2=0
y=-2

The center of your circle will be at (-1, -2).

To find the radius of the circle, square root the 16.

The equation of a circle is x^2+y^2=r^2

So square root the 16 to get your radius, which is 4.

To graph the circle, plot the center of the circle, and plot 4 different points directly out from the center that are 4 units out. Then connect the dots :)

What is the volume of the composite figure shown? (Use 3.14 for π.)

$The\ volume\ of\ the\ cone:V_1=\frac{1}{3}\pi r^2 H\\(r-a\ radius;\ H-height)\\------------------\\r=7ft;\ H=7ft\\\\V_1=\frac{1}{3}\pi\cdot7^2\cdot7=\frac{1}{3}\pi\cdot343=\frac{343}{3}\pi\ (ft^2)\\-------------------\\The\ volume\ of\ the\ cylinder:V_2=\pi r^2 H\\(r-a\ radius;\ H-height)\\-------------------\\r=7ft;\ H=6ft\\\\V_2=\pi\cdot7^2\cdot6=294\pi\ (ft^3)\\------------------------\\The\ volume\ of\ the\ composite\ figure: V_F=V_1+V_2$

$V_F=\frac{343}{3}\pi+294\pi=\frac{343}{3}\pi+\frac{294\cdot3}{3}\pi=\frac{343}{3}\pi+\frac{882}{3}\pi=\boxed{\frac{1225}{3}\pi\ (ft^3)}\\\\\approx\frac{1225}{3}\cdot3.14}=\frac{3846.5}{3}\approx\boxed{1,282.17\ (ft^3)}\leftarrow answer$

$a_1=4\\
a_2=2*a_1=8\\
a_3=2*a_2=2^2*a_1=4*4=16\\
a_4=2^3*a_1=8*4=32\\
a_5=2^4*a_1=16*4=64\\

4+8+16+32+64=124

How do you find the surface area of a cylinder

Nina [5.8K]

You multiply the circumference by the diameter then you solve for the circles on the top and bottom the add them up.
