8.What is the lateral area and the surface area of the cone shown below? Round the answers to the nearest tenth.the figure is no

leonid [27]

Answer:

Part 1) The lateral area is $LA=791.7\ ft^{2}$

Part 2) The surface area is $SA=1,244.1\ ft^{2}$

$LA=791.7\ ft^{2}$ , $SA=1,244.1\ ft^{2}$

Step-by-step explanation:

step 1

Find the lateral area of the cone

we know that

The lateral area of the cone is equal to

$LA=\pi rl$

we have

$r=12\ ft$

$l=21\ ft$

substitute

$LA=(3.1416)(12)(21)=791.7\ ft^{2}$

step 2

Find the surface area of the cone

we know that

The surface area of the cone is equal to

$SA=\pi r^{2}+LA$

we have

$r=12\ ft$

$LA=791.7\ ft^{2}$

substitute

$SA=(3.1416)(12)^{2}+791.7=1,244.1\ ft^{2}$

-3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 if x=2 and y=-1

Vladimir [108]

If $x=2,y=1$ the formula becomes:
$-3(2)^2 + 2\times1^2 + 5(2) - 2 + 5(2)^2 - 3\times1^ 2\\=(-12+2)+(10-2)+(20-3)\\=(-10+8)+17\\=-2+17\\=15$
