The leash will serve as the radius of the circle that Adrianne's dog will be running around on.
radius = 9 feet long
Area = π r²
Area = π (9ft)²
Area = π 81ft²
Circumference = 2 π r
Circumference = 2 π 9ft
Circumference = 18ft π
The circumference of the circle that the dog will be forming when it runs around his leash is 18ftπ and the area it will cover will be 81ft²π.
15^2 = x^2 + 11^2
225 = x^2 + 121
Subtract both sides 121
225 - 121 = x^2 + 121 - 121
104 = x^2
x = √104
x = √4 × 26
x = √4 × √26
x = 2 × √26
x = 2 √26
Answer:
The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds.

Answer:
SQUARE 1:
100% ; 75%
Step-by-step explanation:
SQUARE 1:
If each square represents a whole ; the percentage of a whole = 100%
Dividing the square into 4 equal parts :
Percentage of each part :
100% ÷ 4 = 25%
Percentage represented by the shaded part:
(Percentage of each shaded part * number of shaded part)
(25% * 4) = 100%
SQUARE 2:
each square represents a whole ; the percentage of a whole = 100%
Dividing the square into 4 equal parts :
Percentage of each part :
100% ÷ 4 = 25%
Percentage represented by the shaded part:
(Percentage of each shaded part * number of shaded part)
(25% * 3) = 75%
