We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.
This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.
To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:
A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)
Answer:
1 and twenty thirty sixths
Step-by-step explanation:
14 1/8 - 12 5/9
1/8x4/4=4/36
1/8= 4/36
5/9x4/4= 20/36
14-12= 2
2-20/36= 1 20/36
Answer:
It isn't much help, but the answer is NOT C. 6
I just took the test and C was not the answer !! I will update this if I figure out what it was.
This is a bit harder. I suggest getting the Domain and Range for the function of x.
If any of these answers have, an infinite domain and (3, infinite) range. That will be your answer.
Your answer is B.
f(x) = 2x²+3 has the same domain and range as x²+3
Answer:
46 degrees, they are equal. Hope that helped! (would appreciate being brainliest)
