Hi, thank you for posting your question here at Brainly. To solve this problem, use this formula: F = P(1+i)^n, where F is the future worth, P is the present worth, i is the annual interest and n is the number of years. Substituting the values,

F = $200 (1+0.2)^3
F = $345.6

The answer is $345.6.

jeka57 [31]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

6525\text{cm.}^3

Keep in mind that this is APPROXIMATE.

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Volume of a Sphere Is:}}\\\\V = \frac{4}{3} \pi r^3\\----------------\\\rightarrow \text{We are given the radius of } 11.6\text{ cm.}\\----------------\\V = \frac{4}{3}(3.14) (11.6)^3\\\\V = \frac{4}{3}(3.14) 1560.896\\\\V \approx 6534.95125\text{cm.}^3\\\\\boxed{V \approx 6535\text{cm.}^3}

Can someone please help me on this
PtichkaEL [24]

Well we know that all the sides are congruent so you can use SSS

There are two sides and one angle that is congruent therefore SAS

You have pairs of legs that are congruent so  LL

Lastly we know that JK and QR are congruent so you get HA

Hope this helps :)
