Answer: 26.13yards^2
Step-by-step explanation:
To find the area of the bottom part we can use the diameter.
6 yards. Divide it by half to have the Radius.
Now we use the formula to find the area of a circle which is
A = 3.14*R^2 Pie times radius squared.
A = 3.14*3^2
A = 3.14*9
A = 28.26 Now that we have the area of the circle divide it by 2.
14.13
Now to find the area of an isosceles triangle we use the formula
A = Base * Height Divided by 2.
A = 6*4/2
A = 24/2
A = 12
12 + 14.13 = 26.13
(4/9)/x = 12
(4/9) = 12x
Divide both sides by 12
(1/27) =x
Answer: 48
Step-by-step explanation: COB and DOA are vertical angles. This means the two of them have the same measure. Because we know the measuremen of DOA, we can easily find the measuremen for COB since these angles are the same, so COB is 48 degrees.
(7+4) = 11 so 11 squared (11×11) is 121. The correct answer is 121
