Answer:

The answer in the procedure

Step-by-step explanation:

we know that

The lateral area of a cone is equal to

LA=\pi rl

where

r is the radius of the base

l is the slant height

we have

r=5\ cm

l=6\ cm

assume \pi =3.14

substitute the values

LA=(3.14)(5)(6)=94.2\ cm^{2}

This value is an underestimate, because the assumed pi value is less than the real value

assumed value \pi =3.14

real value \pi =3.1415926536...

Subtract the polynomials (7.8x - 3.4y + z) and (-9.2x + 4.8y - 2.1z), then place the answer in the proper location on the grid.
Naya [18.7K]
Subtracting the polynomials will give us:
(7.8x-3.4y+z)-(-9.2x+4.8y-2.1z)
=(7.8x+9.2x)+(-3.4y-4.8y)+(z+2.1z)
=17x-8.2y+3.1z

Answer: 17x-8.2y+3.1z
