Step-by-step explanation:
a) here,
diametre = 19 cm
Area = ?
Now,
Area = pie d
= 22/7 *19
59.71 cm2
Therefore, area = 59.71 sq.cm.
b)
here,
Area = 1000 sq.cm
diametre = ?
Now ,
Area = pie d
1000 = 22/7 *d
7000 = 22 * d ( cross multiply between 7&1000)
7000/22 = d
318.18 = d
Therefore, diametre = 318.18 cm .
3y-3y+-4=9y-3y-8
-4=6y-8
-4+8=6y-8+8
4=6y
y=4/6
y=2/3 (66.6%)
Answer:
569.49$
Step-by-step explanation:
7.25% = .0725
530.99 x 0.725 = 38.50
530.99$ + 38.50$
569.49$
Answer:
Length of rectangular lawn =72 meters
Breadth of rectangular lawn =18 meters
Perimeter of rectangle =2(Length+Breadth)
So, Perimeter of rectangle =2(72+18)=2(90)=180 meters
If three shrubs can be planted in a meter of hedge.
Then, Number of shrubs planted in whole perimeter will be=3×180=540
Step-by-step explanation:
If there were 1000 sheets of paper, then the thickness of each sheet would be 1.875 in divided by 1000.
1.875/1000 = 0.001875
Since there are 500 sheets of paper, each one is twice as thick as 0.001875, so each sheet is 0.00375 inches thick. 0.015 is much greater than 0.00375, so it must be incorrect.
