The formula for circumference is
or
. We have a diameter for the semicircle, so let's use the diameter formula.
which is either
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069

Step-by-step explanation:
Answer:
11,448 in²
Step-by-step explanation:
The area can be computed from ...
... A = 2(LW +H(L+W))
For the given prism, the area will be ...
... A = 2(18·12 +14(18+12)) = 2(216 +420) = 1272 . . . . in²
The area of a similar figure with dimensions 3 times as long will be 3² times as much. The area of the new figure is ...
... A = 3²×(1272 in²) = 11,448 in²
Yes, it would be correct because a triangle has to add up to 180 degrees when all the angles are added up
A) Explanation:
95 + 10 + 75 = 180
B) A triangle will always add up to 180.
