The total area of a circle and a square is 5450 cm2; the diameter of the circle is 70 cm, what is the difference between the circumference of the circle and perimeter of the square?
r = 35 cm, side of the square = a cm As per the question, 22/7 × r2+ a2= 5450 22/7 × (35)2+ a2= 5450 3850 + a2 = 5450 a2= 1600 a = 40cm Required Difference = 2 × 22/7 × 35 - 4 × 40 = 220 – 160 = 60cm
300% of (3341 – 471) = ? × (√4225/195)
If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
135÷ 15 x 19 + 14807 = ? + √3249 - √9604
7(1/5) – 3(1/4) + 8(3/4) = ?
(6.013 – 20.04) = ? + 9.98% of 5399.98
`sqrt(5476)` + 40% of 1640 = ?`xx` 4 - 2020
(1296) -3/4 = ?
[192 ÷ 6 × 5] ÷ (? + 3) = 20
7(1/2) – 3(5/6) = ? − 2(7/12)
