A = 2πrh + 2πr^2 is the formula. Where A = surface area, r = radius, and h = height. So all we need to know is the outer radius, which is 3.5. Hope this helps you.

Answer:

f(x)=3x-5

g(x)=-6x²+6x+2

f(x)×g(x)

=(3x-5)(-6x²+6x+2)( use distributive property)

=(3x×-6x²)+(3x×6x)+(3x×2)+(-5×-6x²)+(-5×6x)+(-5×2)

=(-18x³)+(18x²)+6x+30x²-30x-10

=-18x³+18x²+6x-30x+30x²-10

=-18x³+18x²-24x+30x²-10

=-18x³+18x²+30x²-10

=-18x³+48x²-10---------------you may write this answer

Hope it's was clear,

Find the area of a regular hexagon with side length 10 m. Round to the nearest tenth.

Maksim231197 [3]

Answer:

$A=259.8\ m^2$

Step-by-step explanation:

we know that

The area of a regular hexagon is the same that the area of 6 equilateral triangles

The area of 6 equilateral triangles applying the law of sines is equal to

$A=6[\frac{1}{2}b^2sin(60^o)]$

where

b is the length side of the regular hexagon

we have

$b=10\ m$

substitute

$A=6[\frac{1}{2}(10)^2sin(60^o)]$

$A=259.8\ m^2$
