Olin [163]

Answer:

Hence By End of the year with monthly compounded interest it will have 5522.56 $

Step-by-step explanation:

Given:

Initial investment =5.280 $

Rate of interest =4.2%

To Find:

Amount after the 1 year

Solution:

As the investment follows the rule for compound interest as ,

A=P(1+R)^t

Here A=amount after t years

R= rate of interest , P= principal amount   t is time period

So given is monthly compounded interest

so t will divided into 12 parts as there 12 months in one year.

P=5280 $ , R=4.2/12 %  , t=12

A=5280(1+0.045/12)^(12)

A=5280(1.00375)^12

A=5280(1.046)

A=5522.56 $

The surface area of a given cone is 1,885.7143 square inches. What is the slang height?
nasty-shy [4]

This question is not complete. This is because it lacks the appropriate diagram containing necessary information to solve this question.

Please find attached the appropriate diagram to solve for this question

Complete Question :

The surface area of a given cone is 1,885.7143 square inches. What is the slant height?

Answer:

25 inches

Step-by-step explanation:

In the diagram, we are given the following information

Height of the cone = 20 inches

Radius of the cone = 15 inches.

The formula for the slant height of a cone represented by l =

l² = r² + h²

l = √(r² + h²)

l = √(15² + 20²)

l = √(225 + 400)

l = √625

l = 25 inches

Therefore, the slant height of this cone = 25 inches
