Answer:
$448
Step-by-step explanation:
We can use the simple interest formula for this:
<em>P = initial balance</em>
<em>r = annual interest rate</em>
<em>t = time</em>

First, change 4% into its decimal form:
4% -> -> 0.04
Now, lets plug in the values:
The total amount in the account after 3 years will be $448
The radius of this circle is (B) 4.9 cm.
<h3>To find the radius of the circle:</h3>To solve this problem, we need to, first of all, convert the angle from radians to degrees.
data;
- length of an arc = 18cm
- angle = 7/6π rads
- π= 3.14
Length of an Arc:
The formula for the length of an arc is given:
θ/360 ×
Let's substitute the values and solve:
From the calculations above, the radius of this circle is 4.9cm.
Therefore, the radius of this circle is (B) 4.9 cm.
