Maria has decided to invest to help with her retirement savings. How much would she have to invest to have $113,400 after 20 yea
Ipatiy [6.2K]

Answer:

$56,226

Step-by-step explanation:

x = investment

Earning interest of 3.57% is the equivalent of multiplying the initial balance (investment) by 1.0357;

Over 20 years, the new balance can be found by multiplying the initial balance by (1.0357)²⁰;

We can formulate an equation to solve to get the initial investment:

x(1.0357)²⁰ = 113400

(2.01687752)x = 113400

x = ¹¹³⁴⁰⁰/₍₂.₀₁₆...₎

x = 56225.5263 → 56226

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.
Tamiku [17]
You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
V=540=\pi r^2*h= \pi r^2*15
Then,
r^2= \frac{540}{15 \pi }
So, r= \sqrt{\frac{540}{15 \pi }}
radius is approximately 3.4cm
*If you cannot see the equations properly please wait till it downloads or refresh the page*
Hope this helps.
