If P(2,3) and Q)2, 5) are points on a graph, calculate the length PQ
6 units
5 units
4 units
2 units
Correct answer is D
\(\sqrt{(x_2 - x_1)^2 + (y_2 - Y_1)^2}\)
= \(\sqrt{(2 - 2)^2 + (5 - 3)^2}\)
= \(\sqrt{0^2 + 2^2}\)
= \(\sqrt{4}\)
= 2 units
Calculate the gradient (slope) of the joining points (-1, 1) and (2, -2)
-1
\(\frac{-1}{2}\)
\(\frac{1}{2}\)
1
Correct answer is A
Gradient = m = \(\frac{y_2 - y_1}{x_2 - x_1}\)
= \(\frac{-2 -1}{2 + 1}\)
= \(\frac{-3}{3}\)
= -1

No explanation has been provided for this answer.
If the total surface area of a solid hemisphere is equal to its volume, find the radius
3.0cm
4.5cm
5.0cm
9.0cm
Correct answer is B
T.S.A of hemisphere = 3\(\pi r^2\)
vol of hemisphere = \(\frac{2}{3} \pi r^3\)
3\(\pi r^2\) = \(\frac{2}{3} \pi r^3\)
3 = \(\frac{2}{3}r\)
9 = 2r
r = \(\frac{9}{2}\)
r = 4.5cm
4.55 litres
7.50 litres
8.10 litres
9.55 litres
Correct answer is A
Vol of a cubiod = L x b x h
v = 13cm x 10cm x 70cm
= 9100cm
Since it is half-filled = \(\frac{9100}{2}\)cm
= 4550cm
4550cm \(\to\) 4.55 litres
