Answer:

Step-by-step explanation:
From the question we are told that:
Radius 
Height 
Rate 
Surface Radius 
Generally the equation for Volume is mathematically given by

Since radius to height ratio gives



Therefore


Generally the equation for Change of Volume is mathematically given by





<u><em>Answer: A. 30. x=30/ 30=x *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
subtract by 15 both sides of an equation.
x+15-15=45-15
simplify.
45-15=30
30+15=45
45-30=15
x=30 and 30=x
Hope this helps!
Thanks!
Have a great day!
Answer: 1106.13 (2 decimal places)
Step-by-step explanation:
To work out the area of this composite shape you would have to put the two semi circles together to form a circle and work out the area of the circle (they have provided the radius which is 11in), then work out the area of the rectangle separately.
The formula for the area of a circle is πr^2 (pi x radius squared).
So when you put the numbers in the formula the area is πx11^2=380.1327111
Then to work out the area of the rectangle you would do base x height.
The height of the rectangle is the same as the diameter of the circle (the diameter is double the radius of a circle) which is 22in.
To find the area of the rectangle you do 22x33=726
So then to find the area of the whole shape you would have to add the area of the circle and the rectangle together.
726+380.1327111=1106.13 (2 decimal places).
Answer:
Yes she has enough walnuts for her two recipes
Step-by-step explanation:
Total number of walnuts that Marni has = 11 ounces
She has two receipe
First recipe = 6 ounces
Second recipe = 1/4 pounds
Hence,
To find out if she has enough:.we add up the number of ounces from both recipes
The second recipe is in pounds hence, we convert to ounces.
1 pound = 16 ounces
1/4 pound =
Cross Multiply
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
Hence, we can add up now
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
Since both recipes would require a total of 10 ounces of walnuts and Marin has 11 ounces, we can conclude that Marin has enough ounces of walnuts for her two recipes.
