I think this the correct solution. but please correct me if I'm wrong
Answer:
35 lol
Step-by-step explanation:
a = b*h/2
a = 10*7/2
a = 70/2
a = 35 lol
The circumference of a circle is found with the equation
C = 2 pi * r
Since we have the circumference we can find the radius. Then once we have the radius we can determine the diameter.
9619 = 2 (22/7) r
multiply each side by 7
67333 = 2*22*r
67333 = 44r
divide each side by 44
r = 67333/44 = 1530.295 rounded to the nearest hundredth = 1530.30
The diameter is 2 x the radius, so
1530.30 x 2 = 3060.6 ft
The diameter of the crater is 3060.6 ft
ANSWER
EXPLANATION
A basic sine curve has equation in the form:
Where 'a' is the amplitude.
In this case a=2 because the amplitude is 2.
For a transformed sine function, the general equation is:
where a=2 is still the amplitude
This is also a sine function with an amplitude of 2.

Answer:
Given the value of pi (π) = 3.14
Given the speed of Radius = 0.10 mph
Given the total area = 11000 square miles.
To find = the time.
Step-by-step explanation:
Since the oil spill in the ocean and spread in a circular pattern. So the total the spilled area = 11000 square miles.
The speed of the radius at which is increase = 0.10 mph
Given the value of pi (π) = 3.14
Now we have to find the total hours consumed to cover the area or the spilled over the area.
First, find the radius and this radius will be the distance. Then divide the distance with speed to find the time taken.
Area = 2 π r^2
11000 = 2 ×3.14 × r^2
r = 41.85 m
Now find the time.
Time taken to spill the oil = 41.85 / 0.10 = 418.52 hours
