If you solve for radius you get 7. Therefore the diameter of the cone would equal 14.
Answer: 85.13
Step-by-step explanation:
We know:
Circumference = 2*3.14r
Area of a circle = 3.14r²
We need to find the radius given the circumference before solving for the area:
32.7 = 2*3.14r
32.7/6.28 = 6.28r/6.28
r = 5.20700637
Now that we know the radius, we can plug it in to find the area:
A = 3.14(5.20700637)²
A = 3.14(27.1129153)
A = 85.134554
Answer:
0.395 kilometers
Step-by-step explanation:
Please consider the complete question.
On Martin's first stroke, his golf ball traveled 4/5 of the distance to the hole. On his second stroke, the ball went into the hole. Martin was standing 79 meters from the hole as he took his second stroke. How many kilometers from the hole was Martin when he started?
Let x represent the distance between hole and start point.
In 1st stroke ball traveled 4/5 of the distance, so 1/5 of the distance was remaining from 2nd stroke to hole. This means the 1/5 of whole distance between start point and hole is equal to 79 meters.
We can represent this information in an equation as:



Since our distance is in meters, so we will convert 395 meters into kilometers by dividing by 1000.

Therefore, Martin was 0.395 kilometers from the hole, when he started.
Answer:
$360
Step-by-step explanation:
To calculate simple interest (I) use the formula
I = 
Where P is the principal (deposit), R is the rate of interest and T is time in years.
here P = 3000, R = 4 and T = 3, hence
I =
=
= $360
