Answer: 1.428 lts of water each day.
1 week includes 7 days so we can say,
7 days --> 10 liters of water
1 day --> 10/7 liters of water
= 1.428 liters of water
Brainliest pls if it was correct!
Answer:
8 pens
Step-by-step explanation:
<h2><u>Finding the number of pens bought </u></h2>
pencil costs 0.27
pen costs 0.32
6 * pencils + x pens = 4.18
6 * 0.27 + x * 0.32 = 4.18
1.62 + 0.32x = 4.18
0.32x = 4.18 - 1.62
0.32x = 2.56
x = 2.56/0.32
x = 8
<u>hence 8 pens were bought </u>
Answer:
central angle=18
arc length=2.5 π feet
area of a sector=31.25π square feet
Step-by-step explanation:
Given
wheel radius=25 feet
attached cars=20
Space between cars along the circumference of wheel= 360/20
=18
Finding arc length:
arc length= radius x angle(in radians)
angle in radian = 18 x π/180 = 0.1π radians
arc length = 25 x 0.1π
=2.5π feet
Area of the circle = πr^2
Area of the circle = π(25)^2
Area of the circle = 625π square feet.
As the ratio of the central angle to the full circle angle is proportional to the area of the sector to the complete circle:
central angle/360=area of sector/area of circle
Area of sector= area of circle x 18/360
= 625π(1/20)
=31.25π !
Answer:
See the picture.....
AS PRIME FACTORS OF 90[2&5 didnt get another 2 or 5 to pair up with] CANT FIND A PAIR TO SQUARE THEMSELVES UP, 90 IS NOT A PERFECT SQUARE
V=hpir²
solve for h just for fun
divide both sides by pir²
v/(pir²)=h
given
v=86.21
r=2.8
pi=3.141592
86.21/(3.141592*2.8²)=h
3.5=h
answer is 3.5ft
