What is the volume of this regular three dimensional figure?
160cm2
48cm2
120cm2
40cm2
Correct answer is B
Volume of the three dimensional figures = v = A x h
A = \(\frac{1}{2}\) x 4 x 3
= 6cm2
V = 6 x 8
= 48cm2
In the figure PT is a tangent to the circle with centre at O. If PQT = 30o, find the value of PTO
30o
50o
24o
12o
60o
Correct answer is B
FROM the diagram, PQT = 50o
PTQ = 50o(opposite angles are supplementary)
In the diagram, if PS = SR and PQ||SQ, what is the size of PQR?
25o
50o
55o
65o
75o
Correct answer is B
In the figure, PQR is a straight line. Find the values of x and y
x = 22.5o, y = 33.75o
x = 15o, y = 52.5o
x = 22.5o, y = 45.0o
x = 56.25o, y = 11.5o
Correct answer is A
\(\frac{3}{2}\)x + 3y + 45° = 180°
3x + 6y + 90° = 360°
3x + 6y = 270.......(i) x 2,
5x + y + y = 180°
5x + 2y = 180° ... (ii) x 6
6x + 12y = 540 ... (iii)
30x + 12y = 1080 ... (iv)
eqn(iv) - eqn(iii)
24x = 540
x = 22.5° and y = 33.75°
11o
19\(\frac{1}{3}\)o
33\(\frac{1}{3}\)o
91\(\frac{1}{3}\)o
91o
Correct answer is B
Adding the values of all the items together, it gives 70
Okro sector = \(\frac{145}{270}\) x \(\frac{360^o}{1}\)
= 19.33o
= 19\(\frac{1}{3}\)o
