A triangle is placed in a semicircle with a radius of 9 cm
julsineya [31]
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17

127.17 - (1/2 x 18 x 9) = 46.17cmsquared

6.5 + (−2) + 10.5 I could probably do this but its kind of hard to understand. Explain?
elena-s [515]
Hello! Let's work this problem from left to right to make things a bit easier ;)

6.5+(-2) is the same as 6.5-2, since adding a negative is the same as subtracting a positive. 6.5-2=4.5

Now, we have to add 10.5 to 4.5, which gives us the grand total of 15. I hope this helped! Let me know if you need anything else!

Suppose you are trying to find your longitude
Alex73 [517]

Answer: 5:15:23 pm

Step-by-step explanation:

There are different time zones in the world due to the Earth's rotation as this results in different parts of the Earth receiving sunlight at different times.

GMT is used as a basis to find the times of other zones.

In this instance, EDT time is -4 that of GMT.

This means that EDT is 4 hours behind GMT.

Time in GMT is therefore:

=  1:15:23 + 4 hours

= 5:15:23 pm
