The answer as a fraction is 6/11
Answer:
Radius = 2.5 m Length = 7 m Half cylinder formula- ½ (pi r^2) + (2 pi R h) Pi x 2.5^2 + 2 x pi x 2.5 x 7
129.5906969 x .5 = 64.795348 m^2 The surface area of the half pipe is 65 m^2.
Answer:
<u> </u><u>The</u><u> </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u><u> </u><u>is</u><u> </u><u>7</u><u>0</u><u>°</u><u>.</u>
Step-by-step explanation:
Let's name the angle to the right of 125° as 'y'.
y = 180 - 125 (linear pair)
<u>y = 55</u>°
Now, we know that all the angles in a triangle sum up to 180°. (Angle Sum Property)
x = 180 - (55+55)
x = 180 - 110
<u>x</u><u> </u><u>=</u><u> </u><u>7</u><u>0</u><u>°</u>
