Answer:
42.43 
Step-by-step explanation:
<u>Given</u>:
A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.
Question asked:
What is the area of the shaded region as shown in the figure ?
<u>
Solution:</u>
First of all calculate area of circle and then area of rectangle:-
As here length an width both are 11 cm, we can say that this is a square.
= 
<u>Now, area of shaded region = Area of square - Area of circle</u>
= 121 - 78.571 = 42.429
Therefore, the area of the shaded region will be 42.43
Part (a)
Replace every 'a' with 5.2 and replace every 'b' with 4.7
Then use your calculator to evaluate.
3a + b^3 = 3*5.2 + (4.7)^3 = 119.423
<h3>Answer: 119.423</h3>
===============================================
Part (b)
The true value is 119.423 which is the result of part (a)
The estimated value is 140
Subtract the two values
140-119.423 = 20.577
and divide that over the true value
20.577/140 = 0.14697857142858
Which, when rounded to 4 decimal places, we get 0.1470
Move the decimal place over to the right 2 spots to get 14.70%
<h3>Answer: 14.70% error (approximate)</h3>
Answer:
Step-by-step explanation:
Hope this helps.
When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
ABC is an isosceles triangle.
Sides : AB = BC
3 x - 7 = 2x
3 x - 2 x - 7 = 2 x - 2 x
x - 7 = 0
x - 7 + 7 = 0 + 7
x = 7
Segment AC:
AC = 3 * 7 - 7 = 21 - 7 = 14
Answer: C ) 14
