12.56. The formula for the area of a circle( radius squared time pie) No, when u double the radius the area quadruples because your squaring the radius.
Overall, answer of XY is 12.165
Answer:
23.54 m
Step-by-step explanation:
Applying
cos∅ = adjacent(A)/hypotenuse(H)
cos∅ = A/H................ Equation 1
make H the subject of the equation
H = A/cos∅............ Equation 2
Given: A = 15 m, ∅ = 25°
Substitute into equation 2
H = 15/cos25
H = 16.55 m
Also,
tan∅ = opposite(O)/Adjacent(A)
tan∅ = O/A............Equation 3
Make O the subject of the equation
O = Atan∅.......... Equation 4
Substituting into equation 4
O = 15(tan25°)
O = 6.99 m.
From the diagram,
The height of the goal post before snap = H+O
The height of the goal post before snap = 16.55+6.99
The height of the goal post before snap = 23.54 m
Answer:
2
Step-by-step explanation:
Step-by-step explanation:
4k - 6 < 3k + (k - 1)
4k < 3k + 6(k - 1)
4k < 3k + 6k - 6
4k < 9k - 6
4k - 9k < -6
-5k < -6
k < <u>-</u><u>6</u>
-5
k < <u>6</u>
