Answer:
(A.) 1/9
Step-by-step explanation:
So there are 9 options to choose from and the question asked about 2 of them.
I took those 2 and multiplied them by 9 which gave me 18.
So I put 2 over 18 which can be simplified by 2.
So my final answer was 1/9.
Answer:
66 square inches
Step-by-step explanation:
First we have to find out the area of the original piece of metal. Since it is 9 by 9, we can multiply to find that it is 81 square inches. If we remove a 5 by 3 piece, which is equal to 15 square inches, we can subtract 15 from 81 to get the answer - the remaining metal is 66 square inches
Answer:
1π
Step-by-step explanation:
suppose the radius of semicircle P is r,
then the radius of semicircle Q = (r+d)/2 ... d≤r
radius of semicircle R = (r-d)/2
area P = 1/2 (r)²π
area Q = 1/2 ((r+d)/2)² π = 1/8 (r² + 2rd + d²)π
area R = 1/2 ((r-d)/2)² π = 1/8 (r² - 2rd + d²)π
shaded area = P-Q-R = 1/2 r²π - 1/4 (r² + d²)π
= ((r² - d²)/4) * π
because there is no constant r value in the question and d value changes with the r change, when the vertical segment length equal the semicircle P radius (r), r=2 and d = 0
therefore the shaded area = ((2² -0²)/4)*π = 1π
