Hello!
To find the lateral area you use the equation
You put in the values you know and you get 829.4
To find the surface area you use the equation
Put in the values you know and you get 1209.5
The answer is A
Hope this helps!
Answer:
the answer is -33 srry couldn't explain :(
I believe it's always a parallelogram??
In triangle ABC,
AC = 12/ (sin30) = 12 / (1/2) = 24
DC = 24-x
DB = DC tan 30 = (24-x) tan30 <span>=(24−x)/</span><span>√3
</span>
In triangle ADB using Pythagorean Theorem<span><span>x2</span>+((24−x)/<span>√3</span><span>)2</span>=<span>12^2</span></span><span><span>x2</span>+(24−x<span>)^2</span>/3=<span>12^2</span></span><span>3<span>x2</span>+(24−x<span>)^2</span>=432</span><span>4<span>x2</span>−48x+576=432</span><span>4<span>x2</span>−48x+144=0</span><span><span><span>x2</span>−12x+36=0
x1 = x2 =6
AD = AC - DC = 24- (24-x) = 6</span></span>
3 (inches) / 6 (hrs) = 1/2 (or 0.5) inches per hr <==
