A=pi *r^2=pi *(D/2)^2=3,14*D^2/4
⇒D^2=4*A/3,14=4*50/3,14=200/3,14≈63,7
D≈V63,7
X^2-7x-4x+28+6+3x-2x-x^2
=> -10x+34
This is the simplest form I can think of.
Answer:
B° is the interior angle
Step-by-step explanation:
An interior angle is an angle that is formed when two sides of a polygon share an endpoint. Therefore, B° is the interior angle because it is formed when the two sides of the polygon shown share the same endpoint.
Answer:
x = 2
Step-By-Step Explanation:
It is really easy to see that the angle on the left side is almost equal to 90° (Right Angle) but is a bit less.
35 × 1 + 3 = 38 F It is too less than 90°
35 × 2 + 3 = 73 T It is closer and less than 90°
35 × 3 + 3 = 108 F It is close but more than 90°
35 × 4 + 3 = 143 F It is too much more than 90°
So,
x = 2
Double Checking
(180° - (35° × 2 + 3)) + (2 + 39°) + (3 + 30°)
= (180° - 73°) + 41° + 32°
= 107° + 41° + 32°
= 180°

Answer:
2 1/4
Step-by-step explanation:
To find the difference, we must subtract the smaller number from the bigger one. In this case, the equation is 12 2/4 - 10 1/4.
Let us set aside the fraction and subtract 10 from 12 first.
12 - 10 = 2
Therefore, the whole number of the difference will be 2.
Let's solve for the fraction now.
2/4 - 1/4 = 1/4
Therefore, the fraction in the answer will be 1/4.
Add 2 and 1/4 to get 2 1/4, which is the answer.
