- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2

Answer:
after sprouting it lived for 100 days
Step-by-step explanation:
Answer:
This means that the correct initial value problem for the population p(t) as a function of time is is
Step-by-step explanation:
The population of a town increases at a rate proportional to its population:
This means that this situation is modeled by the following differential equation:
In which k is the growth rate.
By separation of variables, the solution is given by:
In which P(0) is the initial population.
Initial population of 1000.
This means that the correct initial value problem for the population p(t) as a function of time is is
I think x = 78
because 21/14 = 1.5
so x = 1.5*52
x = 78
A(r)=3.14r^2, when r=5
A(5)=3.14(5^2)
A(5)=3.14(25)
A(5)=78.5 u^2
