Now, since I don't want to actually work hard in class, I fail purposely to stay in normal and not advanced. However this is just a algebraic problem with fractions. Add 2/3 to both sides, (I dont know what that gives you) you then have t = whatever. Hope this helpful! :D <span />

You saved $1,240 and your sister agrees to put it in a savings account at her credit union so you can earn interest. You earned

leva [86]

The amount after 2 years is $2,295.

Given that,

The invested amount is $1,240.
The rate of interest is 8%.
The number of years is 2 × 4 = 8

Based on the above information, the amount after 2 years is

Future value = Present value ×(1 + rate of interest)^number of years

= $1,240 × (1 + 0.08)^8

= $1,240 × 1.08^8

= $2,295

Therefore we can conclude that the amount after 2 years is $2,295.

SashulF [63]

Answer:

The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.

Step-by-step explanation:

Given : In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m.

To find : The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter ?

Solution :

Radius of each pillar r= 42 m

Height of each pillar h= 7 m

The curved surface area of each pillar is $CSA=2\pi rh$

Substitute the value,

$CSA=2\times \frac{22}{7}\times 42\times 7$

$CSA=1848\ m^2$

Area of 30 pillars is given by,

$A=1848\times 30=55440\ m^2$

The curved surface area of all pillars at the rate of Rs.10 per square meter.

The cost painting is $C=55440\times 10=Rs.554400$

Therefore, the total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
