6.28cm
12.6cm
22.6cm
62.8cm
Correct answer is B
Length of arc = \(\frac{\theta}{360 \times 2 \pi r}\)
= \(\frac{72}{360} \times 2 \times \frac{22}{7} \times 10\)cm
= 12.57
= 12.6cm(3 s.f)
If the pass mark was 4. What percentage of the pupils failed the test?
20.0%
37%
62.5%
80.0%
Correct answer is A
No. of pupils that failed = 1 + 3 + 4 + 8
% failed = \(\frac{8}{40} \times 100\)% = 20.0%
How many pupils took the test?
36
38
39
40
Correct answer is D
No. of pupils = 1 + 3 + 4 + 7 + 8 + 6 + 6 + 4 + 1 = 40

Correct answer is B
area of larger circle = 100\(\pi\)
\(\pi r^2 = 100\pi\)
R2 = 100
R = 10(Radius)
Area of smaller circle = \(49 \pi\)
\(\pi r^2 = 49\pi\)
r2 = 49
r = 7(radius)
Since R = x + r
x = R - r
x = 10 - 7 = 3
