Answer:
254
Step-by-step explanation:
first find the diameter of the big circle by adding the 2 founded numbers
which is 18
then the Radius = 9
to find area,
which is
Answer:
The correct answer is option C. 490 units ²
Step-by-step explanation:
Area of cuboid = 2(lb + bh + lh)
From the figure we can see that a rectangular prism.
<u>To find the surface area of prism</u>
Here l = 14 units
b = 7 units and h = 7 units
Surface area = 2((14 * 7) + (7 * 7) + (14 * 7))
= 490 units ²
The surface area of the triangular prism is 93 squared feet.
<h3>What is the
surface area of the
triangular prism?</h3>
The surface area of triangular prism is expressed as;
S.A = bh + ( s₁ + s₂ + s₃ )H
From the diagram;
- h = 2ft
- b or s₁ = 3ft
- s₂ = 3ft
- s₃ = 3ft
- H = 10ft
We substitute our given values into the equation above.
S.A = bh + ( s₁ + s₂ + s₃ )H
S.A = (3ft × 2ft) + ( 3ft + 3ft + 3ft )10ft
S.A = 3ft² + ( 9ft )10ft
S.A = 3ft² + 90ft²
S.A = 93ft²
The surface area of the triangular prism is 93 squared feet.
