Answer:
Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625
Step-by-step explanation:
(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.
5 ÷ 2 = 2.5
2.5² = 6.25
π = 3.14
3.14 x 6.25 = 19.625)
Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!
<u>The right and left shaded regions areas are 6.28 each.</u>
4 ÷ 2 = 2
2² = 4
3.14 x 4 = 12.56
Since this is a semi circle, we cut it in half.
12.56 ÷ 2 = 6.28
To find the top and bottom shaded region's areas, repeat the same steps.
3 ÷ 2 = 1.5
1.5² = 2.25
3.14 x 2.25 = 7.065
7.065 ÷ 2 = 3.5325
<u>The areas of the the top and bottom shaded regions are 3.5325 each.</u>
Step-by-step explanation:
Firstly we have to take variables to L.H.S and numbers to R.H.S
Hope it helps
<span>1. We assume, that the number 96 is 100% - because it's the output value of the task. </span>
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 96 is 100%, so we can write it down as 96=100%. </span>
<span>4. We know, that x is 33% of the output value, so we can write it down as x=33%. </span>
5. Now we have two simple equations:
1) 96=100%
2) x=33%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
<span>96/x=100%/33%</span>
Answer:
Step-by-step explanation:
The area of a circle is expressed as
Area = πr^2
Where r = radius of the circle
π = constant = 3.14
The radius of a circle is increased from 8.00800 to 8.03803 m. This means that the original radius of the circle is 8.00800 and the new radius of the circle is 8.03803
Area of original circle =
3.14 × 8.00800^2 = 201.36212096
Area of new circle =
3.14 × 8.03803^2 = 202.87516852203
Increase in area = 202.87516852203 - 201.36212096
= 1.51304756203
Expressing the change as a percentage, it becomes
1.51304756203/201.36212096 ×100
Percentage change = 0.75 %
