Answer: 21.994 cm²
Step-by-step explanation:
Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142
Now area of the bigger circle = 3.142 x 3²
= 3.142 x 9
= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2
= 6.284 cm².
Therefore are of the shaded region = 28.278 - 6.284
= 21.994 cm²
Answer:
C = -10x+3
Step-by-step explanation:
So the simplified version of the main expression is -10x+3. after finding the main expression you just need to simplify the rest of them too.
A. = -10x+9
B. = 8x-9
C. = -10x+3
D. = -10x-3
Now that you simplified all the expressions, you can pick out the one that's the same as the target expression, which is C.
Answer:
5
Step-by-step explanation:
150/30 = 15/3 = 5
Good luck!
Answer:
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Step-by-step explanation:
Given
- Initial velocity u = 10 m/s
To determine
Acceleration a = ?
Using the formula to determine the acceleration
a = (v - u) / t
substituting u = 10 m/s, v = 0 and t = 5
a = (0 - 10) / 5
a = -10 / 5
a = -2 m/s²
Thus,
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
This is easy onystly I think you should do it your self but the answer is number b
