A is the answer because the key word is TOTAL and EACH
Answer:
Below in bold.
Step-by-step explanation:
First find the height by use Pythagoras theorem on the right triangle:
h = sqrt (5^2 - 4^2)
= sqrt 9
= 3.
Volume of the prism = area of the triangle * length
= 1/2 * 3 * 4 * 10
= 1/2 * 12 * 10
= 60 cm^3.
Total area = area of 2 triangles + area 0f 3 rectangles
= 2 * 1/2 * 3 * 4 + 3 * 10 + 4 * 10 + 5 * 10
= 12 + 30 + 40 + 50
= 132 cm^2.
Answer:
Step-by-step explanation:
The volume of a cylinder, 
is given by the formula,
Where, 
is the radius and 
is the height of the cylinder.
Here, 
, 
. Plug in these values and solve for radius, .
This gives,
Taking square root both sides, we get
Therefore, the radius of the cylinder can be expressed as .
