Hey there! I'm happy to help!
If something is 11 less, we are subtracting 11.
-11
We have 11 less than seven times a number x.
7x-11
The word is means equals.
7x-11=-4
Now we need to isolate the x. We add 11 to both sides.
7x=7
We divide both sides by 7.
x=1.
Have a wonderful day! :D
Answer:
113.10 if you use the pi button
113.04 if you use 3.14
Step-by-step explanation:
We want to find the volume
V = 4/3 pi r^3
The radius is 3
V = 4/3 pi (3)^3
Using the pi button for pi
V = 113.09734
Rounding to the nearest hundredth
V = 113.10
If you use 3.14 for pi
V = 113.04
Answer:
<em>1) the exact distance = 9.428571429 feet</em>
<em>the approximate distance = 9.4 feet</em>
<em></em>
<em>2) the exact area = 7.071428571 ft^2</em>
<em>the approximate area = 7 ft^2</em>
<em></em>
Step-by-step explanation:
Required diameter d = 3 feet
1) The distance around the outside of the pit is the circumference of the circle that will be formed by this circular fire pit.
circumference of a circle is given as = πd = 
x 3 = 9.428571429 feet
the exact distance = 9.428571429 feet
the approximate distance = 9.4 feet
2) The area of the circle that will be formed = 
= 
= 7.071428571 ft^2
the exact area = 7.071428571 ft^2
the approximate area = 7 ft^2
Answer:
132 cm^2
Step-by-step explanation:
Find all areas and add together.
A = L x W
tA = (L x W)/2
30 + 30 + 48 + 12 + 12 = 132
Answer:
56
Step-by-step explanation:
area of whole figure=
l×b
=20×10
=200
also,area of small fig.
=l×b
=18×8
=144
thus area of shaded part =a of whole- a of small
=200-144
=56
