Len [333]

Answer:

V=8.5

Step-by-step explanation:

o=oil. vinegar=v. furniture polish=f

O=3v

34= 3v + v

Using a system of guessing and checking if that number fits equation you can tell that 8 causes the equation to be unequal and also 9. You can learn V must be between 8 and 9 so 8.5 might fit the equation. 8.5=V

Answer:

The surface area of the cone $=238.64feet^2$

Step-by-step explanation:

The given figure is in the shape of a cone:

$Diameter=8 feet\\\\Radius=8/2=4 feet$

slant height(l) $=15 feet$

Surface area of the cone

= $\pi rl+\pi r^2$

As, $\pi =\frac{22}{7}=3.14$

Surface area of the cone = $(3.14*4*15)+(3.14 *4*4)$

$=(3.14*60)+(3.14*16)\\\\=188.4+50.24\\\\$

$=238.64feet^2$

The surface area of the cone $=238.64feet^2$
