Note: As you can see on the attached picture, I've split the shape into three chunks. By comparing the sides and using some subtraction I came up with some information that will make the problem easier and wrote it in green. If you have any problems following my logic there, feel free to send me a message of comment under this and I'll elaborate.

Left Most Chunk:
-The formula for finding the area of a circle is A=πr^2. In this problem we are finding 1/4th of a circle so the formula would look like A=1/4(πr^2).
-Radius(r): 9
-Work:
A=1/4(πr^2)
A=1/4(π9^2)
A=1/4(π81)
A=1/4(π81)
keeping in mind to use 3.14 for pi...
A=1/4(254.34)
A=63.585 sq ft

Middle Chunk:
-This is basic area finding (Lenghth x Width)
-Work:
A= l x w
A = 13 x 6
A= 78 sq ft
————
Right Most Chunk:
-This is basic area finding (Lenghth x Width)
-Work:
A= l x w
A = 7 x 5
A= 35 sq ft
————
Total Area:
-Work:
63.585 + 78 + 35 =
176.585

Answer: 176.585 square feet
Y = tan (√ t )
We will use chain rule.
( tan x ) ` = sec² x
( √ t ) ` = 1 / 2√t
y ` = sec² (√ t ) · 1 / 2√t
y` = 1/cos² ( √ t ) · 1 / 2√t
Since we know we are working the variable x we can use it in the followng. Twice the numbers means 2x, and plus 4.
We can write this into an equation: 2x + 4
Best of Luck!
Given:
Circle with center P.
To find:
Which statement is true.
Solution:
In the circle P,
- PT is a radius of the circle P.
- VU is a diameter of the circle P.
- SR is a secant of the circle P.
- NQ is a tangent line and Q is a point of tangeny of circle P.
Option A:
N is a point of tangency on circle P.
It is is not true because Q is a point of tangency of circle P.
Option B:
PT is a secant of circle P.
It is not true because PT is a radius of the circle P.
Option C:
SR is a secant of circle P.
It is true by the above bulleted points.
Option D:
VU is a tangent of circle P.
It is not true because VU is a diameter of the circle P.
Therefore SR is a secant of circle P is a true statement.
Answer:
Correct solution:
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64
Step-by-step explanation:
they rode 45.7, 40.9, and 38 miles
= (45.7 + 40.9 + 38) miles
= 124.6 miles
Convert 124 .6 miles to kilometers
1 kilometer = 0.621 miles
124.60 miles = 124.60 / 0.621
= 200.64 kilometers
This is the correct solution because he divided 124.60 miles by 0.621
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64
