Need additional information, which is the height and which is the diameter of the cylinder from the measurements supplied? Standard forumula for locating Radius and Volume of a cylinder are as follows.
Radius=Diameter/2
Volume=Base X height
Base= 3.14*r*r
Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.
Hope this helps
Answer:
Start with y=mx+b since it is perpindicular to the slope of -3/4 the new slope is 3/4. so now we have m=4/3 next we subsitute known values in (0,-1). We multiply 0 by 3 next we have -1=0+b so be has to be -1 so your awnser is
y=4/3-1
You have 40/16
simplified by 8 and you have 5:2
so the answer is d. 5:2
Answer:
The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)
so
we have
---> the radius is half the diameter
substitute the given values
Round up to the nearest whole number
therefore
The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
