The formula for area is:
Area = Length * Width
96 = L * 3
L = 96 / 3
L = 32
The surface area of a sphere is given by the formula: 4πr².
Substituting r = 7 cm, we get 4 × 3.1416 × (7)² = 616 cm².
Any number divided by a non-zero whole number follows the basic division rule: 0 ÷ any number = 0.
Division by zero is undefined, but dividing zero by a number results in zero.
The sum of the first 10 natural numbers is:
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
OR
Formula for natural number= n(n+1)/2
n=10
Now
10(10+1)/2
10(11)/2
5(11)
55
The number of diagonals in a polygon can be calculated using the formula:
n(n-3)/2
where n is the number of sides.
For a 12-sided polygon (dodecagon):
n = 12
Number of diagonals = 12(12-3)/2
= 12(9)/2
= 108/2
= 54
Decrease = 25,000 - 24,500 = 500
Percentage decrease = (500 / 25,000) × 100 = 2%
Identify the given values: The sum of observations is Sum=1500
. The number of observations is n=30
Average = Sum of observations / Number of observations
= 1500 / 30
= 50
A decade consists of 10 years.
It is a period of ten consecutive years.
Given log₁₂(12³) = x:
Using logarithm properties, logₐ(aⁿ) = n:
x = 3
Natural Number: The number 1 is considered a natural number (used for counting: 1, 2, 3, ...).
