Answer:

C. 176.6 Square feet (I think)

Step-by-step explanation:

I tried many different ways and got three of the answers above but I think this is the right one.

The equation to find area of a circular cone base: $A= \pi r^2$

We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: $r = \frac{d}{2}$
Plug in numbers: $r=\frac{15}{2}$ ≈ $7.5$
Use the Area formula now that you have radius: $A=\pi 7.5^2$
Solve and get = $a = 176.71458676$
Looking at the options the closest one to our answer (off by one-tenth) is C.

Sorry if you get this wrong. I tried lol.

How do i work out 6x+6=0

VMariaS [17]

Answer: X= -1

Step-by-step explanation: In this equation you want to solve for "x"

You subtract 6-6=0 leaving "x" by itself. So the equation will look like this: 6x= -6

After this you want to divide by 6 to one side and to the other equaling "x" as -1
