Answer:
Area of a circle- <em>pi </em>x <em>r </em>square
3.14 x 2 x 2
= 3.14 x 4
= 12.56
Round off- 13
X = 12 subtract then divide both sides
Answer:
x = 10
The second number is 50
Step-by-step explanation:
Givens
The first number = x
The second number = 5x
Together when added the answer is 60
Equation
x + 5x = 60 Combine like terms
Solution
6x = 60 Divide by 6
6x/6 = 60/6
x = 10
