Answer:
you multiply the circumference by the radius squared
Ex.) (c= circumference)
c=3.14x2r
Answer:
Explanation:
(3/14)k - 1 - 4 - (2/7)k = 0
(3/14)k - (4/14)k - 5 = 0
(-1/14)k = 5
-k = 5 x 14
k = -70
Answer:
m<-2
Step-by-step explanation:
-4m-3.65>4.35
-4m>4.35+3.65
-4m>8
4m<-8 (the greater than or less than sign flips when you multiply or divide by the - sign)
m<-2 (divide both sides by 4)
Radius of the circular tent (r) = 3 m
Area of the floor = Area of circle =

r²

= 3.14
Area of the floor = 3.14 x 3² = 28.26 m²
