Question
The surface area of a sphere is
given as (12474/25) cm². Calculate the diameter of the sphere. (Use π = 22/7)Solution
ATQ,
Let the radius of the sphere be 'r' cm. Surface area of sphere = 4 × π × r2 ATQ; r = 63/10 = 6.3 {Since, radius cannot be negative} So, diameter of the sphere = 6.3 × 2 = 12.6 cm
236.23 - 653.23 + 696.23 = ?
Simplify:
Simplify the following expression:
(506 ÷ 22 + 9 × 3) × ? = 900 ÷ 9
What will come in place of (?) in the given expression.
√625 + 12 × 5 = ?[(15)³ × (8)²] ÷ (90 × 6) = ?²
(√529 + 63 /8)% of 800 = ?% of 250
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
Simplify the following expression:-
25% of {(5/18) × 2880 + 122 } = ?% of 590
