Answer:

1134.1 [cm²]

Step-by-step explanation:

A=πr2

Circle area = π * r² = π * 361 [cm²] ≈ 1134.1 [cm²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 19 [cm] * 2 = 38 [cm]

QUICK PLEASE. Calculate the final amount if $10 000 invested for 6 years at 4% compounded quarterly.
Nikolay [14]

The final amount if $10 000 invested for 6 years at 4% compounded quarterly is $12,697

<h3>Compound interest</h3>

The formula for calculating the compound interest is given as:

A = P(1+r/n)^nt

Given the following parameters

A = 10000(1+0.04/4)^4(6)

A = 10000(1+0.01)^24

A = 10000(1.01)^24

A = 1.2697(10,000)

A = $12,697

Hence the final amount if $10 000 invested for 6 years at 4% compounded quarterly is $12,697

What is the value of the expression 3p (4p +5) + 3 for p= -1 is<br>plzzzzzzzz i want it fast
AleksAgata [21]

Answer:

0

Step-by-step explanation

well at least thats my guess!

we have to go by bidmas. so you substitute first!

so its going to be: 3(-1)(4(-1)+5)+3

all I did is that I replaced all p's by -1 and then you multiply it!

so its gonna be: -3(-4+5)+3

you first solve what's in the brackets which is -4+5 so the answer is 1 like this: -3(1)+3 now its much simpler. all we have to do is to expand the bracket so its going to be -3+3 so the answer is 0!
