Answer:
82.97cm^2
Step-by-step explanation:
Given data
Circumference= 131.88 centimeters
We want to find the area of 6/10 part of a circle
Firstly, let us find the area of the circle
We need to get the radius
C= 2πr
131.88= 2*3.142*r
131.88=6.284r
r= 131.88/6.284
r=20.98 cm
Area= πr^2
Area= 3.142*20.98^2
Area= 3.142*440.16
Area= 1382.98cm^2
Hence 6/10 of a 1382.98
=0.06*1382.98
=82.97cm^2
Answer:
60 degrees
Step-by-step explanation:
The sum of the angles in a triangle are 180 degrees. The angles look the same size, so divide 180 by 3, and you get 60 degrees
Yo has to factor since we assume that
if you have xy=0, x and y=0
7n^2-48n+36=0
trial and error
(7n-6)(n-6)=0
set each to zero
7n-6=0
add 6
7n=6
divide 7
n=6/7
n-6=0
add 6
n=6
n=6/7 or 6
Answer: 267.7
I just did the math and I got this answer
2x+y=3
- x+y=5
---------------
x=-2
2(-2)+y=3
y=7
-2+y=5
y=7
(-2,7)
