Two solid spheres have volumes 250cmo and 128cmo respectively. Find the ratio of their radii.
125:64
25:16
2:1
4:3
5:4
Correct answer is E
96cm2
108cm2
135cm2
162cm2
216cm2
Correct answer is D
A = 1/2(A + B)h = 1/2(24 + 12) x 9 = 162
\( \frac{\pi x^2}{8} \)
\( \frac{3\pi x^2}{8} \)
\( \frac{5\pi x^2}{8} \)
\( \frac{3\pi x}{8} \)
Correct answer is B
A = θ 360 x πr2 = 135 360 x π x x2 = (3πx2)/8
2.3cm
4.6cm
8cm
16cm
16cm
Correct answer is B
Length of arc = \(\frac{\theta}{360} \times 2\pi r\)
= \(\frac{75}{360} \times 2 \times \frac{22}{7} \times 3.5\)
= \(4.583 cm\)
\(\approxeq\) 4.6 cm (to 2 sig. figs)

10,000km
6,400km
5,000km
3,200km
Correct answer is B
D = θ/360 x 2πR
