Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
Answer:
20,250
Step-by-step explanation:
To find certain percentage of a number, we first convert the percentage into decimal and then multiply that decimal with the number.
<u>Converting Percentage to Decimal Rule:</u>
- Divide the percentage by 100
So, 30% would become:
30/100 = 0.3
Now, we multiply:
0.3 * 67,500 = 20,250

Answer:
He has got Rs. 800 discount
Step-by-step explanation:
x - the price
20%x = 0.2x - the discount
x-20%x = 80%x = 0.8x - price after discount
10%•0.8x = 0.1•0.8x = 0.08x - VAT to pay
0.08x = 320
x = 320:0.08 = 4000
0.2x = 0.2•4000 = 800
