2) You need pi because of the circumference to calculate how long the perimeter is.
3) 113.1 = Area
4) You would need to adjust how many number places of pi you use for how huge the number you need to calculate for.
5) To write an exact number for an irrational expression you need to calculate then round to the nearest hundredths after you get the number for either radius, diameter, or area. To find the approximate value you only use the minimum numbers such as 3.14 instead of 3.14159...
6) How this helped me better estimate the value of an irrational expression is by using more numbers for every extra number place the circle has in the diameter.
Answer:94°
Step-by-step explanation:
The sum of the interior angles of the polygon: 180°(n-2)
180°(5-2)=540°
The sum of the interior angles of the pentagon is 540°
So:
P+Q+R+S+T=540°
(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°
4x+2+4x-10+5x-11+260=540
13x=299
x=23°
P=4x+2°=4×23°+2°=94°
Answer:
what is the area of a triangle with a base of 2 5/8mm and a height of 10mm
Step-by-step explanation:
C.16 3/8mm2
28.7251 =
28 degrees
then take the decimal and multiply by 60 to get the minutes
so 0.7251 *60 = 43.506, use the whole number (43)
so now you have 28 degrees, 43 minutes
now take the remaining decimal ( 0.506) and multiply by 60
0.506*60= 30.36
when you have a decimal left over for the seconds, keep that as is.
so you now have 28 degrees, 43 minutes and 30.36 seconds
use ' for minutes and " for seconds
28 degrees 43' 30.36"
Your equation is 3n = 201.
You have to isolate n so divide 3 to 201.
201/3 = 67.
