Question
A sector of a circle has a central angle of 120° and a
radius of 10 cm. Find the area of the sector.Solution
The area of a sector of a circle is given by: Area = (θ / 360) * πr², where θ is the central angle. Area = (120 / 360) * π * 10² = (1/3) * π * 100 = 100π / 3 ≈ 33.33π cm².
√3598 × √(230 ) ÷ √102= ?
15% of 2400 + (√ 484 – √ 256) = ?
(13)2 - 3127 ÷ 59 = ? x 4
6269 + 0.25 × 444 + 0.8 × 200 = ? × 15
...(53 + 480 ÷ 4)% of 20 = ?% of 70
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
√ [? x 11 + (√ 1296)] = 16
11 × 25 + 12 × 15 + 14 × 20 + 15 = ?
