Answer:
radius = 1
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 2)² + (y + 3)² = 1 ← is in standard form
with r² = 1 ( take the square root of both sides )
r = 
= 1
Step-by-step explanation:
-5=u+6
-5-6=u
-11=u
therefore , u= -11

Answer: 1680 inches cubed
Step-by-step explanation:
Volume = Length x Width x Height
V = 20 x 7 x 12
V = 140 x 12
V = 1680 inches cubed
Anna= a
Vickie= v
Luanna= l
a is 3 years older that v
l is 2 years younger than v
Anna's age; 3+v
Luanna's age; v-2
