Answer:
37.14 units
Step-by-step explanation:
the whole circumference of a circle is 2×pi×r
a whole circle rotates 360 degrees (one time all around).
so, the length of the arc for a full trip (360 degrees) around a circle is the stated 2×pi×r.
now, if we go only for a part of that full trip angle, the arc is only the corresponding part of the circumference.
in our example here, r (radius) = QR = 19 units
and we only go along the circle for 112 degrees out of the full 360 (112 parts of the whole 360).
so the arc QS = 2×pi×19 × 112/360 = 37.14 units
To solve this question we will use the following diagram:
From the diagram, we get that the diameter of the semicircle is 8cm.
The perimeter of the figure is:
Substituting π=3.14 and simplifying we get:
Now, the area of the given figure is the area of the rectangle plus the area of the semicircle:
Substituting π=3.14 and simplifying we get:
Answer:
Answer:
116 degrees
Step-by-step explanation:
well from the picture we know this is a 45 45 90 style triangle therefore in if CBE is equal to 32 then ECB should also be equal to 32 leaving you with a total number of 64 degrees within the triangle. and in every triangle you must add up the degrees to 180 so if we subtract 64 from 180 we get 116 degrees for BEC
