Answer:
r=0.079577a or a/4
Step-by-step explanation:
a=(4)(3.141593)r
Step 1: Flip the equation.
12.566371r=a
Step 2: Divide both sides by 12.566371.
<u>12.566371r</u>
12.566371
=
<u>a</u>
12.566371
= 0.079577a
Answer:
$130.06
Step-by-step explanation:
Interest is calculated as shown;
I = A - P
A is the amount
P is the principal
Given
Principal = $316
Rate R = 9% = 0.09
Time t = 4yrs
Substiutte and get Amount A
A =P(1+r)^n
A = 316 (1+0.09)^4
A = 316(1.09)^4
A = 316(1.4116)
A = 446.06
Interest = 446.06 - 316
Interest = 130.06
Hence the interest is $130.06
