We know that
[area of a circle]=pi*r²---------> r=√[area/pi]
for
A=95.03 m²
r=√[95.03/pi]--------> r=5.50 m
[circumference]=2*pi*r------> 2*pi*5.5--------> 34.56 m
the answer is
34.56 m
There are 42 cats, and 49 dogs at animal shelters because I know that 6:7 will have total 13 parts, and I just need to take 91 divided for 13 to get 7 for each part, and to find how many cats are there; I just need to take 7 times 6 to get 42 cats, and take 91 subtract for 42 to get 49 dogs. Hope it help!
Step-by-step explanation:
a=2
b=-7
c=-15
-(-7)+-sq root (-7)²-4(2)(-15) / 2(2)
7 +- sq root 169 / 4
7+- 13 / 4
7+13 / 4, 7-13 / 4
x=5 x=-3/2
All of your marked answers are right
you're very smart (:
