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
Answer:
AAS
Step-by-step explanation:
Area = b * h
Area of orange = area of big square subtract by area of small square
Small square = b^2
Big square = a^2
(a^2 - b^2) = (a - b)( a + b)
Solution: (a - b) (a + b)
Answer:
128
Step-by-step explanation:
There are 32 50's in 1600.
So 32x4=128
Answer:
no, they are not functions
Step-by-step explanation:
this is because a single domain has multiple range.
i.e. domain 2 has ranges 2 and 4
