Answer:
284.3
Step-by-step explanation:
Trapezoid Formula:
A=a+b/2*h
plug in the numbers
There is 180 degrees in a triangle. We know two of the angles are 50 degrees. 180-50= 130 which is X.
Simply use the formula they give you. For question 6, 4 is the radius. So the area of the circle is 4pi. Now for seven you do the same thing, but they gave you the diameter instead and it’s a half circle. So try that one on your own. Let me know if you get stuck
Basically apply your radius and slant height to the formula to find the surface area of a cone which is S=3.14r^2+3.14rl
Answer:
6
Step-by-step explanation:
3=x/2
Multiply both sides by 2
