Answer:
3 cm
Step-by-step explanation:
Set up an equation that solves for the surface area, "112
" :
10(2)+10(2)+2x+2x+10x+10x = 112
20+20+4x+20x = 112
24x+40=112
24x=72
x=3
So, 3 cm.
Here you go.................
Answer:
X = 4
Step-by-step explanation:
5x =61-6
5x= 55
X = 55/5
X = 11
Try going through the formula which is 2 pi r
so 2*3.14*7
