Question
If the height of equilateral triangle is 12 cm, then
find out the area of its circumcircle?Solution
Height of an equilateral triangle = √3/2  × side Side = h × 2/√3 = 12 × 2/√3 = 8√3 Radius of circumcircle = side/√3 = (8√3)/√3 = 8 cm Area of circumcircle = πr² = 8²π = 64π
?% of 18% of 2600 = 234
22 – 15 + 20 × 18 ÷ 6 – 34 = ?
390/? = √256 + 3.5
(65% of 120) = 25% of ? - 22
((0.1)3+ (1.8)3+ (1.1)3 - 0.3 ×1.8 ×1.1)/((0.1)2+ (1.8)2+ (1.1)2- (0.18)- ...
(5.6 + 2.4 + 13.8 – 2.8) × 5 = ? × (12.5 – 7.5)
29% of 400 + 66% of 1100 - 50% of 1200 = ?Â
12% of 152 + 12% of 150 = ? of 5
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
154 × 7 + 480 × 5 =?% of 6956
