Answer:
The diameter is 14
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is 49 pi
49 pi = pi r^2
Divide each side by pi
49 pi/ pi = pi r^2/pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 =r
We want the diameter
d = 2r
d = 2*7
d = 14
No he already did because his smsnebejsks in the graph is in orget
1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
have a merry christmas :)
When the son is 8, the father is five times that so 8*5 = 40, difference between their ages is 32
twice as old 32*2 = 64
The father will be 64.
If we use the place value chart, 10020 and 20010 will be further dissected based on place values. At first look, 20010 seems to have more tens and that is fact; but this method will show us that it is otherwise so follow the solution below carefully:
Employing PLACE VALUE CHART:
For 20010:
*10000 <--- Ten-thousands place.
*10000 <--- Ten-thousands place.
*10 <--- Tens place.
Add these numbers and you will get: 20010. 20010 has two ten-thousands place and one tens place.
For 10020
*10000 <--- Tens-thousands place.
*10 <--- Tens place.
*10 <--- Tens place.
Add these numbers and you will get: 10020. 10020 has one ten-thousands place and two tens place.
Therefore, there are more tens in 10020 than in 20010.
