In the diagram above, O is the center of the circle. If ∠POR = 114o, calculate ∠PQR
123o
118.5o
117o
114o
54o
Correct answer is A
Reflex POR = 2PQR
Reflex PQR = 360o - 114o = 246o
PQR = 246/2 = 123o
2.44cm
4.89cm
9.78cm
25.1cm
50.3cm
Correct answer is B
Circumference of circle = 2πr = 2 x 3.14 x 4
= 25.1cm 360o = 25.1cm
If logax = p, express x in terms of a and p
x = u + p
x = a/p
x = p
x = ap
x = ap
Correct answer is E
\(\log_{a} x = p\)
\(x = a^p\)
11.25cm2
12.83cm2
22.0cm2
67.2cm2
90.2cm2
Correct answer is E
r = 3.5 cm; l = 8.2 cm.
Curved surface area = \(\pi rl\)
= \(\frac{22}{7} \times \frac{7}{2} \times \frac{41}{5}\)
= 90.2 cm\(^2\)
(0,6), (3,9)
(-3, 0)(2,4)
(-2,4)(3,9)
(-2,3)(-3,2)
(-2,2)(3,6)
Correct answer is C
From the graph; when x = -2, y = 4
(-2, 4)
x = 3.0, y = 9; (3,9)
(-2, 4)(3,9)
