Answer:
8 meters.
Step-by-step explanation:
Let the 2 radii be x and 2x, then
π x^2 + π (2x)^2 = 80π
π x^2 + π 4x^2= 80π
x^2 + 4x^2= 80
5x^2 = 80
x^2 = 16
x = 4.
So the radius of the larger circle = 2*4 = 8 m.
Answer:
Converse: if 5=x then x+2=7
Inverse: if x+2 doesnt = 7 then x isnt 5
Contrapositive: if x doesnt equal five then x plus two doesnt equal seven

Answer:
$51.30
Step-by-step explanation:
76 decrease 25% =
76 × (1 - 25%) = 76 × (1 - 0.25) = 57
57 decrease 10% =
57 × (1 - 10%) = 57 × (1 - 0.1) = 51.3
Answer:
Circumference : 18.84 inches
Radius: 3 inches
