Illustrate a detailed mathematical still life. The main components should be a three-dimensional cone, with the radius of 8 represented by a wooden ruler and the height of 7 shown using loose string measurement. Include symbolic representations of the concept of surface area for a cone, such as a net diagram containing a circle and a sector. Pin a card alongside with pi approximated to 3.14 written on it. The whole arrangement should be similar to a well-lit classroom desk setting, with a chalkboard subtly in the background but devoid of any text.

Find the surface area of the cone. Use 3.14 for pi. The radius is 8in and the height is 7in.

need help

area of sides = pi r L

area of bottom = pi r^2

if the height is 7 and the radius is 8 then the slant height, the hypotenuse
L = sqrt ( 49 +64) = sqrt ( 113 ) = 10.63
the area of the sides is then pi * 8 * 10.63 = 267.2
the area of the bottom is pi *64 = 201.1
the sum = 468.3

i have a question

what part of this do i use in adult life?

Do you guys realise that the diameter is 8 which means the radius is 4. And the slant height is 7 not the regular height

the answer is ~ 468

damon is still right to this day!! thank you guys!! much love stay safe! <3

Damon is correct!

By is right thanks by

B ()732=(57)+y=6a2

Thanks I was making sure pog

Yesoo
