A:
Preview: ... angle (b) as shown (c) as shown Q4 Use Pythagoras' theorem. 1743 * 1743 + 1828 * 1828 = 6379633 2525 * 2525 = 6375625 they are not the same. Hence the triangle is not a right triangle. Q5 (a) sum of all angles = (20-2) x 180 = 3240 degrees sum of each angle = 3240 / 20 = 162 degrees (b) sum of all angles = (37-2) x 180 = 6300 degrees sum of each angle = 6300 / 37 = 170.27 degrees Q6 (a) 4 times larger. Let the radius of the original circle be r. The area = pi * r * r Radius of the doubled circle is 2r. The area = pi * (2r) * (2r) = 4 * pi * r * r = 4 * area of original circle. (b) 25 times larger. Radius of the new circle = 5r. The area = pi * (5r) * (5r) = 25 * pi * r * r = 25 * area of the original circle (c) n*n times larger. Radius of the new circle = nr. The area = pi * (nr) * (nr) = (n*n) * pi * r * r = (n*n) * area of the original circle Q7 Attachment: Q7.gif In the figure, Ac = 6cm and BD = 8cm. Since the diagonals of a rhombus are perpendicular to each other, angle AEB is 90 degrees. Moreover, the diagonals of a rhombus bisect each other, therefore BE = BD / 2 = 4cm. Area of triangle ABC = (BE * AC) / 2 = (4 * 6) / 2 = 12 cm sq. Similarly, area of triangle ADC = 12 cm sq. Therefore, area of rhombus = 12 + 12 = 24 cm sq. Q8 Attachment: Q7.gif (not Q8.gif) In the figure, Ac = d1 an ...
