Area of a circle = 3.14 x r^2
=3.14 x 8.5^2
= 226.865
Answer:
The coordinate of 
is 13.36.
Step-by-step explanation:
According to the statement, we have the following information:
(1)
(2)
(3)
(4)
From (2), we have the following expression:
(5)
If we know that and , then the coordinate of is:
The coordinate of is 13.36.
Answer:
27°C
Step-by-step explanation:
The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.
Answer:
25 in ^2
Step-by-step explanation:
First find the area of the circle
A = pi r^2
A = 3.14 ( 4.3)^2
A =58.0586
The take the fraction of the circle that is shaded
A circle is 360 degrees
155/360
155 /360 * the total area = area shaded
31/72 * 58.0586 = 24.99745278 in ^2
Rounding yields 25 in ^2
