Let the radius of the cone be ‘r’ cm Therefore, (1/3) × (22/7) × r2 × 3.5 = 1617 Or, r2 = 1617 × (7/11) = 441 Or, r = 21 (since, radius cannot be negative) Therefore, radius of the cone = 21 cm
The value of the expression (1 + sec22° + cot68°)(1 – cosec22° + tan68°) is
If the nine-digit number 43x1145y2 is divisible by 88, then the value of (3x — 2y), for the smallest value of y, is:
If 2y cos θ = x sin θ and 2x sec θ - y cosec θ = 3, then the value of x2+ 4y2 is
...If 0 ≤ θ ≤ 90°, and sec107 θ + cos107 θ = 2, then. (secθ + cosθ) is equal to:
If a3 = 117 + b3 and a = 3 + b, then the value of a + b is:
The value of = 3/4 ÷ 3/4 of 4/3 + 5/2 ÷ 2/5 of 5/4 – (2/3 + 2/3 of 5/6) is :
Quantity I – 3
Quantity II – 254
If > 0 and < 0
If x2 + y2 + 2x + 1 = 0, therefore the value of x31 + y35 is
IfX = (√5 + 1) / (√5 – 1) and y = (√5 – 1) / (√5 + 1) then the value of(x 2+xy+y
