Answer:
area of the polygon=1/2×(28+18)×12
=276unit²
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.
Answer:
29 rows.
Step-by-step explanation:
- Turn 11/2 and 3/16 into a fraction
- 11/2 = 5.5 and 3/16 = 0.1875
- Divide 5.5 by 0.1875 = 29.3333333333
- Round up and get 29 since .3333333333 does not equal a whole shelf.
Answer:
The number of bacteria in 0.25 mL is 6.25 x 10^3.
Step-by-step explanation:
5 liter flask contains 1.25 x 10^8 bacteria.
So, 1liter flask contains =
