Answer: $943.11
<u>Step-by-step explanation:</u>
Compound Interest formula is: 
where
- A is the Accrued amount (total earned)
- P is the Principal (amount initially invested)
- r is the interest Rate (convert percent to a decimal)
- t is the Time (number of years)
It is given that; P = 800 r = 4.2% (0.042) t = 4
A = 800(1 + 0.042)⁴
A = 800(1.042)⁴
A = 943.106 → A = 943.11 (rounded to the nearest penny)
Sarah invested $800 for four years at an interest rate of 4.2% and accrued $943.11
It would be an isosceles triangle. Since there are two sides of the triangle that are congruent, it would be isosceles.
Isosceles has two congruent sides, scalene has none, and equilateral has three.
(A good tip to do is this: count the number of syllables in each word. Then take away two. That's how many sides that triangle has.)
Ex: i-so-sce-les has four syllables. Take away two, you get two. Therefore, an isosceles triangle has two congruent sides.

Answer:
213.64 in.^2
Step-By-Step Explanation:
We know, Volume of a Cone = πr² h/3
v = 3.14 * (6)² * 11.4/3
v = 3.14 * 36 * 3.8
v = 429.552
Now, for 1 m³, it costs = $20
So, for 429.552 m³, it will be: 20 * 429.552 = 8591
In short, Your Answer would be $8591
Hope this helps!
