Answer:
Step-by-step explanation:
If point 
divides the segment with endpoints 
and 
in the ratio 
then
In your case,
then
Thus,
In order to find the volume you need the height.
Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height
To find the height you have to divide the surface area by the part I bolded
Height = 1850 ÷ 310.56
Height ≈ 6
Volume of a cylinder = πr²×height
= 3.14 × 9 × 9 × 6
Volume =1526.04
Nearest whole number would be 1526
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
Answer:
From the information, we know that the plate will hold 3 pieces of sushi, each with a diameter of 1 1/2 inches, and there be 1/2 inch space from the edge of the of the suchi to the edge of the plate.
The diamter of the suchi plates we need to puchase should be the sum of the diameter of the sushi and the the space between them and the edge of the plate:
(3 . 1 1/2) + (2 . 1/2)
= (3 . 3/2) + 1
= 9/2 + 1
= 9/2 + 2/2
= 11/2 = 5.5 (inches)
Answer:
At least 22 hours in a week.
Step-by-step explanation:
Given: Manuela make $15 per hour.
Her employers deduct $125 from her weekly check.
Manuela receives at least $205 in her weekly paycheck.
Lets assume, Manuela working hour in a week be "x".
We know, Total amount on week paycheck= 
Now, forming an inequality to determine weekly pay of Manuela.
⇒ 
⇒
Adding both side by 125
⇒
⇒
Divinding both side by 15
⇒
∴
Hence, Manuela works at least 22 hours per week.
