Find the least number of coins of diameter 2.5 cm and height 3 mm which are to bemelted to form a solid cylinder of radius 3 cm and height 5 cm. |
Answer» GIVEN:✰ DIAMETER of each coin = 2.5 cm ✰ Height of each coin = 3 mm = 0.3 cm ✰ Radius of solid cylinder = 3 cm ✰ Height of solid cylinder = 5 cm To find:✠ The least number of coins which are to be melted to form a solid cylinder. Solution:Let's understand the CONCEPT first!
Let's find out...✧ ⇾ Radius of each coin = Diameter/2 ⇾ Radius of each coin = 2.5/2 ⇾ Radius of each coin = 5/4 cm ✭ Volume of each coin = πr²h ✭ Putting the values in the formula, we have: ➛ Volume of each coin = 22/7 × (5/4)² × 0.3 ➛ Volume of each coin = ( 22/7 × 25/16 × 0.3 ) cm³ ✭ Volume of cylinder = πR²h ✭ Putting the values in the formula, we have: ➛ Volume of solid cylinder = 22/7 × 3² × 5 ➛ Volume of solid cylinder = 22/7 × 9 × 5 ➛ Volume of solid cylinder = ( 22/7 × 45 ) cm³ Now,➤ The least number of coins to be needed = Volume of solid cylinder/Volume of each coin ➤ The least number of coins to be needed = (22/7 × 45)/(22/7 × 25/16 × 0.3) ➤ The least number of coins to be needed = 45/(25/16 × 0.3) ➤ The least number of coins to be needed = 450/(25/16 × 3) ➤ The least number of coins to be needed = 96 ∴ 96 coins which are to be melted to form a solid cylinder. _______________________________

ABCD is a square of side 70cm. Four quarter circle are drawn with each vertex ascentre as shown in the figure. Find the area of the shaded region. |
|
Answer» Answer: 1050 sq.cm STEP-by-step explanation: STEP 1 : TO FIND THE AREA OF THE SQUARE. Area of Square = 70 × 70 = 4900 sq.cm STEP 2 : TO FIND THE AREA OF THE FOUR QUARTER CIRCLES. Four quarter circles make a single CIRCLE. So, the radius of the COMPLETE circle is 35 cm. Area of a circle = 22/7 × 35 × 35 = 3850 sq.cm. STEP 3 : TO FIND THE AREA OF SHADED REGION. Area of Square - Area of circle = Area of shaded region. = 4900 - 3850 = 1050 sq.cm Therefore, area of shaded region = 1050 sq.cm Hope it is helpful |

Answer» Answer: The term is closely associated with the work of mathematician and meteorologist Edward LORENZ. He noted that butterfly effect is derived from the metaphorical example of the details of a tornado (the EXACT time of formation, the exact PATH taken) being influenced by minor perturbations such as a distant butterfly flapping its wings SEVERAL weeks earlier. Lorenz discovered the effect when he observed runs of his weather model with initial condition data that were rounded in a seemingly inconsequential manner. He noted that the weather model would fail to reproduce the results of runs with the unrounded initial condition data. A very small change in initial conditions had |
