1. If the diameter of a circle is 7 cm what will be the circumference? (38 cm, 34 cm, 22 cm, 20 cm, none of these)

2. If radius of a circle is doubled then the area of the circle will be : (2 times , 4 times, 6 times, 8 times, none of these) 3. perimeter of a square is Y unit. Find the area of the square. 4. Identify the formula to find the perimeter of an equilateral triangle. ( 2 X side, 3 X side, side+side+side, none of these) 5. Seema makes a triangle ABC in which AB - AC. which one of the following is true. ( 6. A car runs at 30 km/h. After 2 hours the speed of the car is increased by 5 km/h for 3 hours. Find the speed of the car. ( 11 km/h , 22 km/h , 33 km/h , 44 km/h, none of these) 7. A is a natural number. If we divide A by 65 which one of the following can not be the remainder? ( 30 , 50 , 0 , 65 , none of these)

1. 22 cm 2. 4 times 3. (y÷4)² which is y²÷ 16 4. 3 X side, or side+side+side 5. I don't understand. 6. For 2 hours, dist=60 km. For the 3 hours, dist= 105 km. Total Dist.=165 km. Total time= 5 hours. So, avg speed= 165/5= 33 kmph 7. 65, because if there was a remainder of 65, then you will simply divide it by one and leave a remainder of 0.
