Answer:
Step-by-step explanation:
An approximate number, that can be calculated mentally, is by using the rule of 72: Divide 72 by the interest in % to give the number of years needed to double the money.
In this case, the approximate number of years
n= 72/4=18 years (approximately)
Precise value by compound interest formula:
2P=P*(1.04)^n
=>
1.04^n=2
take logs on both sides
nlog(1.04)=log(2)
n=log(2)/log(1.04)=17.673 years
It’s 188.4
All you have to do is plug in 30cm into the formula for circumference :)
Answer:
304.85 cm²
Step-by-step explanation:
The area (A) of a polygon is calculated as
A = pa ( p is the perimeter and a the apothem ) , thus
A = 45.5 × 6.7 = 304.85 cm²
