Answer:
16 pi or approximately 50.24
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
r = d/2 where d is the diameter
r = 8/2 =4
So plugging into the equation for the area
A = pi (4)^2
A = 16pi
Using 3.14 as an approximation for pi
A = 16*3.14 =50.24
Plug in the known information to find the radius
r= radius
Area= πr^2
58= (3.14)r^2
divide both sides by 3.14
18.4713375796= r^2
take the square root of both sides
4.2978294033 feet= r
CIRCUMFERENCE
C= 2πr
C= 2(3.14)(4.2978294033)
C= 26.99 feet (or rounded to 27 ft)
ANSWER: 26.99 feet (or rounded to 27 ft)
Hope this helps! :)
This is
(6(3)^-1 (-5)^0)^-3
= (6/3 * 1)^-3
= (2)^-3
= 1/8 Answer
Answer:
$240
Step-by-step explanation:
I = prt
I = (2,400) (0.04) (2.5)
note: I changed 4% to a decimal and 30 months to 2.5 years
I = 96 (2.5)
I = 240 <-- The interest
------------------------------------------------------------------------------------------------------------
The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

* Last time I did interest was in 6th grade and I don't remember much. So I am very sorry if my answer is wrong *
