Answer:
1000.
it's just 10 times itself twice (10^2) times 10
Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:
Where, r is the radius.
Substituting , we get
Therefore, the exact circumference of the circle is 62.8 feet.
Note: All options are incorrect.
Answer:
The answer is C.
Step-by-step explanation:
First, you have to find the interest amount after 6 years. In order to do this, you have to subtract :
Next, you have to apply simple interest formula, I = (P×R×T)/100 where I repesents interest amount, P is priciple, R is interest rate and T is number of years :
Answer:
Part 1) The perimeter of the park is
Part 2) The area of the park is
Step-by-step explanation:
see the attached figure to better understand the problem
Part 1) Find the perimeter pf the park
we know that
The perimeter of the figure is the sum of its six length sides (see the figure)
so
Part 2) Find the area of the park
The area of the park is equal to the area of two rectangles
The area of rectangle is equal to
substitute the values
