Answer:hehe ion
Step-by-step explanation:I’m sorry✨
Product-the answer found by multiplying to factors
3 X 3=9
We have that
surface area of the cylinder=2*[pi*r²]+[2*pi*r*h]
r=(4x+3)
h=3*r=3*(4x+3)
S=2*[pi*(4x+3)²]+[2*pi*(4x+3)*(3*(4x+3))]------> 2*[pi*(4x+3)²]+[6*pi*(4x+3)²]
S=8*pi*(4x+3)²----> 8*pi*[16x²+24x+9]-----> 402.12 x²+603.19x+226.19
the answer is S=402.12 x²+603.19x+226.19 (8pi[16x²+24x+9])
The storage tank one is 14.99
Half cylinder is 471.239
I don't remember how to do the second one sorry :(
