Find the surface area of the cone in terms of pi.

Nana76 [90]

Surface area of cone is 60π cm^2

Option A is correct.

Step-by-step explanation:

We are given:

Height = 17cm

Radius= 3cm

We need to find surface area of cone in terms of π.

The formula used to find surface area of cone is:

$Surface\,\,area\,\,of\,\,cone=\pi r(r+\sqrt{h^2+r^2})$

Putting values:

$Surface\,\,area\,\,of\,\,cone=\pi r(r+\sqrt{h^2+r^2}) \\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{(17)^2+(3)^2})\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{289+9)}\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+\sqrt{298)}\\Surface\,\,area\,\,of\,\,cone=\pi \,3(3+17)\\Surface\,\,area\,\,of\,\,cone=\pi \,3(20)\\ Surface\,\,area\,\,of\,\,cone=60\pi$

So, Surface area of cone is 60π cm^2

Option A is correct.

If p(x) = 2x2 - 4x and g(x) = x - 3, what is (pog)(x)?

stira [4]

Answer:

Step-by-step explanation:

p(x) = 2x² - 4x

g(x) = x - 3

To find (pog)(x) replace every x in p(x) by g(x)

That's

(pog)(x) = 2(x - 3)² - 4(x - 3)

= 2( x² - 6x + 9) - 4x + 12

= 2x² - 12x + 18 - 4x + 12

Hope this helps you

Help is much appreciated x

RoseWind [281]

Answer:

23.2 cm

Step-by-step explanation:

For the angle of 53.2 deg, x is the opposite leg. The hypotenuse is 29 cm.

sin A = opp/hyp

sin 53.2 deg = x/29 cm

x = 29 cm * sin 53.2 deg

x = 23.2 cm
