we know that
The volume of a cylinder is equal to
where
r is the radius of the base
h is the height of the cylinder
In this problem
For
<u>Find the value of h</u>
<u>Find the volume of the cylinder</u>
therefore
<u>the answer is</u>
The volume of a cylinder is equal to
Answer:
<h2>S.A. = 66m²</h2>Step-by-step explanation:
Look at the picture.
We have :
4 rectangles 3m × 4m → A₁ = 3 · 4 = 12 m²
2 rectangles 3m × 3m → A₂ = 3 · 3 = 9 m²
Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
Substitute:
S.A. = 4(12) + 2(9) = 48 + 18 = 66
