60
=30 cm
Circumference of the wheel =2πr=2×

×60=15.84 km
Hence, the speed with which the boy is cycling is 15.84km/hr.
The answer would be 0.95 totaling 1 as there is only 1 chance that this will happen
Answer: (d)
Step-by-step explanation:
Given
XYZA is a rhombus and side XY is 8 units
We know, In a rhombus
- All sides are equals
- Diagonals bisect each other perpendicularly
Using the above property, we can write
Thus, option (d) is correct.
Answer: 17
Step-by-step explanation:
20. percent *85 =
(20.:100)*85 =
(20.*85):100 =
1700:100 = 17
