A ≈ 3420 cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius ) , then
A = π × 33² = 1089π ≈ 3420 cm² ( to 3 significant figures )
Answer:
5666
Step-by-step explanation:
Given:
P = $500
r = 3.75% = 0.0375

I = Prt
I = ($500)(0.0375)(4)
I = $75
Answer:
The total amount of money in Maria's account after 6 years is $8436
Step-by-step explanation:
Given;
principal amount , P = $5,700
interest rate, r = 8 % = 0.08
time of investment, t = 6 years
The interest on the invested money after 6 years is given by;
I = Prt
I = $5,700 x 0.08 x 6
I = $2736
Total amount in Maria's account is given by;
A = P + I
A = $5,700 + $2736
A = $8436
Therefore, the total amount of money in Maria's account after 6 years is $8436
