Answer:
4 7/20
Step-by-step explanation:
8 1/4 - 3 9/10
get a common denominator of 20
8 1/4 *5/5 - 3 9/10 *2/2
8 5/20 - 3 18/20
borrow 1 from the 8 in the form of 20/20
7 +20/20 + 5/20 - 3 18/20
7 25/20 - 3 18/20
4 7/20
Answer:
radian
Step-by-step explanation:
We know that angle for a full circle is 2
In the given figure shape is semicircle
hence,
angle for semicircle will be half of angle of full circle
thus, angle for given figure = half of angle for a full circle = 1/2 * 2
= 
Thus, answer is
radian
alternatively, we also know that angle for a straight line is 180 degrees
and 180 degrees is same as
radian.
3 becuse you put the numbers wrong
