A piece of wood is designed in the shape of a cone. A cylindrical hole of radius 4 cm and depth 2 cm has been drilled has been drilled into the base The surface area of the wood has to be painted, except for the area inside the hole

Work out surface area to be painted

to find ther surface area of a cone, you use the formula π x r² + π x r x l

Step-by-step explanation:

An in putting the numbers into the variables

r = 4cm

π = 3.14  

So we do π x 4 x 2 + π x r ( there is no length )

and that gives us 25.12 + 12.56 =  37.68cm ( Don't forget the cm!)

hope this helps!

i think it would be c

mark brainliest if im right

step-by-step explanation:

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)
