8800cm2
8448cm2
4400cm2
4224cm2
Correct answer is A
L2 = 962 + 282
= 9216 + 784
= 10000
L = \(\sqrt{10000}\)
= 100cm
curved surface area = \(\pi r l\)
= \(\frac{22}{7} \times 28 \times 100\)
= 8800cm2
area of cone = area of sector
area of sector = 8800cm2
Given that (x + 2)(x2 - 3x + 2) + 2(x + 2)(x - 1) = (x + 2) M, find M
(x + 2)2
x(x + 2)
xv + 2
x2 - x
Correct answer is D
(x = 2)(x2 - 3x + 2) + 2(x + 2)(x - 1) = (x + 2)m
(m + 2)[(x2 - 3x + 2) + 2(x - 1)] = (x + 2)M
divide both side by (x + 2)
(x2 - 3x + 2) + 2(x - 1) = M
x2 - 3x + 2 + 2x - 2 = M
x2 - 3x + 2 + 2x - 2 = M
x2 - 3x + 2x = M
x2 - x = M
M = x2 - x
The distance between two towns is 50km. It is represented on a map by 5cm. Find the scale used
1: 1,000,000
1: 500,000
1: 100,000
1: 10,000
Correct answer is A
1km = 100,000cm
on the map 1 cm represent every 10 km which is equal to (10 x 100,000cm)
= 1,000,000cm
the scale is 1:1,000,000
48cm3
47cm3
38cm3
12cm3
Correct answer is C
Volume of a cone = \(\frac{1}{3} \pi r^2h\)
h2 = 52 = 32
= 25 - 9 = 16
h = \(\sqrt{16}\)
h = 4cm
v = \(\frac{1}{3} \times \frac{22}{7} \times 3^2 \times 4\)
\(\frac{1}{3} \times \frac{22}{7} \times 9 \times 4\)
= \(\frac{22 \times 3 \times 4}{7}\)
= 37.7cm3
= 38cm3
322m3
448m3
632m2
840m2
Correct answer is B
Volume of pyramid = \(\frac{1}{3}\) x base area x height
= \(\frac{1}{3} \times 12^4 \times 8 \times 14\)
= 4 x 8 x 14 = 448m3
