Answer:
C) 101.5 pi in^2
Step-by-step explanation:
A cylinder's area is found by next formula:
This is because the cylinder has two circle bases and its lateral area is a rectangle whose base is the perimeter of a circle and whose height is the cylinder's height. My last step was to take the common factor.
From the figure you get the cylinder's height and the base diameter's length, which is double of radius'. Since we need "r":
Now, we replace height and radius in the formula:
Answer:
The values are
m = 13
b = 17
Step-by-step explanation:
1239 = 94m + b ------eqn 1
810 = 61m + b -----------eqn 2
Let's take eqn 1, let's make b the subject of the formula
1239 - 94m = b
Since b = 1239 - 94m
Insert the value of b into the eqn 2
810 = 61m + (1239 - 94m)
810 = 61m + 1239 - 94m
Collect like terms
810 = 61m - 94m + 1239
810 = - 33m + 1239
810 - 1239 = - 33m
- 429 = - 33m
The minus sign cancels each other
Making m the subject
m = 429 / 33
m = 13
Since we've gotten the value for m, insert the value of m= 13 into the eqn 1
1239 = 94m + b
m = 13
1239 = 94 (13) + b
1239 = 1222 + b
1239 - 1222 = b
17 = b
b = 17
m = 13
b = 17
Answer: 0.6kg of flour will be in each batch of scones.
Step-by-step explanation:
Adam has 16.45 kg of flour, and he used 6.4kg to make hot cross buns. This means that the remaining flour would be the total amount of flour that he had initially minus the the amount that he used to make hot cross buns. This is expressed as
16.5 - 6.4 = 10.05 kg
The remaining flour is exactly enough to make 15 batches of scones. This means that 10.05 kg of flour will be enough to make 15 batches of scones.
We want to determine how much flour, in kg, will be in each batch of scones. Let this amount of flour be xkg
If 10.05 kg of flour will be used to make 15 batches of scones. Then,
xkg of flour will be used to make 1 batch if stones
x = 10.05/15
x = 0.67
