Divide both sides by 1/5, and that's the value of x.
I'm sorry for the double post... why does this keep happening to me?
A=1/2h(b1+b2).
Plug in the values: 36=1/2(4)(10+b2).
18=10+b2.
The length of the other base is 8.
31.4/(3/4)= 41.866666666666666666666 etc...
Fraction form: 41 13/15.
tan 78.3=height/115. (Try to visualize a triangle in your head.)
The monument is about is about 555.314 ft tall.
You could just type this on any calculator you know...
(the * usually is a "x" on most calculators.)
4x+16=24
Subtract 16 from both sides: 4x=8
Divide by 4.
SA of cylinder= 2$${\mathtt{\pi}}$$rh+2$${\mathtt{\pi}}$$r^2, r for radius and h for height.
20$${\mathtt{\pi}}$$+4$${\mathtt{\pi}}$$=24$${\mathtt{\pi}}$$
Surface Area=24$${\mathtt{\pi}}$$ mm^2.
