836cm2
308cm2
528cm2
154cm2
Correct answer is A
Area(S) = 2\(\pi r^2 + 2 \pi rh = 2\pi r(h + r)\)
D = 14cm, 2r = D
r = \(\frac{D}{2}\)
= 7cm
S = 2 x \(\frac{22}{7} \times [7 + 12] = 44 \times 19\)
= 836cm2
PT is a tangent to the circle TYZX. YT = YX and < PTX = 50o. Calculate < TZY
50o
65o
85o
130o
Correct answer is B
XTY = 50o = TXY = \(\frac{130^o}{2}\)
= 65o
Determine the value of x in the figure
134o
81o
53o
46o
Correct answer is A
Within the triangle,
180° - (81° + 53°) = 46°
In a cyclic quadrilateral, the sum of two opposite angles = 180°
\(\therefore\) x = 180° - 46° = 134°
Use the graph of the curve y = f(x)to solve the inequality f(x) \(\leq\) 0
-1 \(\geq\) x \(\geq\) 1, x \(\geq\) 2
x \(\leq\) -1, 1 \(\geq\) x \(\geq\) 2
x \(\geq\) -1, 1 \(\geq\) x \(\geq\) 2
x \(\geq\) 2, -1 \(\geq\) x \(\geq\) 1
Correct answer is B
-1 \(\geq\) x \(\geq\) 1, 1 < x \(\geq\) 2
Combining solutions
= x \(\leq\) 1; 1 \(\geq\) x \(\geq\) 2
