Step-by-step explanation:
50/50 chance of choosing one or the other because there is only two options
Answer:
y=-7-ax
3x-(-7-ax)=17
3x+7+ax=17
3x+ax=10
x(3+a)=10
x=10,3+a=10 a=10-3 a=7
Rectangle
Hope this helps :)
1444.4 m2
Surface Area = 2 * 3.14 * (R*R + R*L) = 2 * 3.14 * (10*10+10*13) = 1444.4 m2
Note .. You can Derive this
"Surface Area = 2 * 3.14 * (R*R + R*L)"
Using Calculus by differentiating its Volume
V = 3.14 * R * R * L
