The volume of a cylinder is V=pi(r^2)L. to find the radius you must first divide the known volume by the known length and pi which is roughly equivalent to 3.14. this is equal to 49 which is equal to the radius squared. finally to find the radius of the cylinder you must take the square root of the radius squared which is 7.
Answer: radius = 7 cm

Answer:
175.2 square feet
Step-by-step explanation:
The lateral area is the total area of the side faces. It excludes the area of the top and bottom "bases" of the prism.
It can be found by adding the areas of the four rectangles. The two you can't see have the same areas as the two you can see.
Since the height of each rectangle is 4 feet. the total area will be the product of that and the perimeter of the prism.
LA = Ph . . . . perimeter times height
LA = 2(L+W)h . . . . the perimeter is twice the sum of length and width
LA = 2(12.3 ft + 9.6 ft)(4 ft) = 2(21.9 ft)(4 ft) = 175.2 ft²
The lateral area of the prism is 175.2 ft².

The attachment shows scribbling on two of the faces that contribute to the lateral area. As stated above, the other two faces are the same size as these.
Answer:X = 15.2
Step-by-step explanation:
-4+5x= 72+4= 76
5x= 76
X = 15.2

Answer:
$17.49
Step-by-step explanation: You need to subtract $30.39 by $12.90
$30.39
<u>-$12.90</u>
First, its 9 - 0 which will = 9.
Then, 3 - 9. but you can do that so you have to make the 3 in 30, into a 2 then make the 0 in 30 a ten, then make that 10 into a 9, then make the 3 into 13.
So 13 - 9 = 4.
Now you have 9 - 2. Which will = 7.
Last, its 2 - 1 which will = 1.
so after all of that you get: $17.49
