Area of a circle = PI x R^2
r = 1/2 diameter
r = 21.5/2
r = 10.75
Area of circle = 3.14 x 10.75^2 = 3.14 x 115.5625 = 362.86625 square units.
A semicircle is half a circle:
Area of semicircle = 362.86625 / 2 = 181.433125 square units (round the answer as needed).
Answer:
175.26 centimeters
Step-by-step explanation:
There are approximately 2.54 centimeters in an inch.
To find how many centimeters are in 69 inches, multiply 69 by 2.54:
69(2.54)
= 175.26
So, approximately 175.26 centimeters are equal to 69"
Answer:
The answers are the 1st, 4th and 5th one. I just took the Test
Step-by-step explanation:
The relationship between lines m & n is (a) the lines M and N have positive slope
<h3>How to describe the relationship?</h3>
The points are given as:
- Line M: (1, 4) and (2, 7)
- Line N: (1, 3) and (, 5)
From the above points, we can see that:
As x increases, the y values of both lines increase
This is an illustration of positive slope
Hence, the lines M and N have positive slope
