Answer:
49π
Step-by-step explanation:
Are of the circle equal π (where π is pi and "r" is the radius). Radius equals the diameter divided by 2. Therefore the area of this circle equals...
π = π = 49π
Answer:
88
Step-by-step explanation:
Write the expression for the sum in the relation you want.
Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)
Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)
The relation we want is ...
Sn > 5543
35(1.06^n -1) > 5543 . . . . substitute for Sn
1.06^n -1 > 5543/35 . . . . divide by 35
1.06^n > 5578/35 . . . . . . add 1
n·log(1.06) > log(5578/35) . . . take the log
n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n
The least value of n such that Sn > 5543 is 88.
The two numbers should be 17 and 51 respectively.
Given that
- Let us assume the other number be x.
- And, the one number be 3x.
- Now if 17 is added to each , so the first number should be twice of the second.
So, the following equation should be
3x + 17 = 2(x + 17)
x + 17 = 2x + 34
x = 17
So, we can conclude that the two numbers should be 17 and 51 respectively.

Answer:
(x+2) + x + (x+4) = 2(1/2) + 2(x+3)
Step-by-step explanation:
They are equal to each other and the rectangle has 2x more perimeter
The triangle would be divided in half from that rectangle.
Sorry If this is confusing I am not very good at explaining things.
I don’t know the answer for sure but i do know for surface area you multiply all the sides together so maybe that will help you. (you would count how many units they go over for each line.)
