Each of the interior angle of a regular polygon is 162o. How many sides has the polygon?
8
12
16
20
Correct answer is D
\(\frac{(n - 2)180}{n}\) = 162 (where n = no. of sides)
162n = 180n - 360
162n - 180n = -360
-18n = - 360
n = \(\frac{360}{18}\)
n = 20
Find the volume of a solid cylinder with base radius 10cm and height 14cm.
2203
880cm3>
1400cm3
4400cm3
Correct answer is D
volume of a cylinder = \(\pi r^2h\)
r = 10cm
h = 14cm
= \(\frac{22}{7} \times 10 \times 10 \times 14\)
= 4400cm3
5\(\frac{1}{2}cm\)
4\(\frac{2}{3}cm\)
3\(\frac{1}{2}cm\)
2\(\frac{1}{3}cm\)
Correct answer is D
Length of arc = circumference of the base of the
cone \(\frac{\theta}{360} \times 2\pi R = 2 \pi r\)
\(\frac{\theta R}{360}\) = r
r = \(\frac{60 \times 14}{360}\)
= \(\frac{7}{3} = 2\frac{1}{3}\)cm
The area of a square field is 110.25m2. Find the cost of fencing it round at N75.00 per metre
N1,575.00
N3,150.00
N4,734.30
N8,268.75
Correct answer is B
Area = 110.252
f2 = 110.25(square)
l = \(\sqrt{110.25}\) = 10.5m
Since N75.00 per metre
N75.00 = 1 metre; x = 10.5m
x = 787.5 for one side, then four sides = N787.5 x 4
= N3,150.00
2.5cm
3.0cm
3.5cm
4.0cm
Correct answer is D
Distance(d) = d2 = 52 - 32
= 25 - 9
= 16
d = \(\sqrt{16}\)
= 4cm
