Answer: 8.76%
Step-by-step explanation:
The formula to find the simple interest is given by :-
, where P is the principal amount, r is rate of interest () in decimal and t is the time ( in years). (1)
Given : Justin deposited $2,000 into an account 5 years ago.
i.e. P = $2,000 , t= 5 years
He has just withdrawn $2,876. i.e. Future value = $2,876
Interest (I)=$2,876-$2,000=$876 [Subtract Principal value from Future value]
Substitute all the above values of P , t , and I in the formula (1) , we get
In percent ,
Hence, the rate of interest = 8.76%
Answer: Circumference of circle = 27.004 inches
Area of circle = 58.0586 inches²
Step-by-step explanation:
Diameter of circle = 8.6 inches
Pi () = 3.14
Circumference of circle (With diameter) = d (
×diameter)
= 3.14 × 8.6
= 27.004 inches
Area of circle (With diameter) = /4
= 3.14 × 8.6 × 8.6 / 4
= 3.14 × 73.96 / 4
= 58.0586 inches²
