The surface area of the smaller solid is 112 km².
<h3>What are Similar Solids?</h3>
Similar shapes are enlargements of two shapes using a scale factor.
The ratio of the volume of similar solids is the ratio of the cube of their length.
Formula:
- V/v = L³/l³................... Equation 1
- L/l = ∛(V/v)............... Equation 2
Where:
- V = Volume of the larger solid
- v = volume of the smaller solid
- L = Length of the larger solid
- l = Length of the smaller solid.
From the question,
Given:
Substitute the value into equation 2
To calculate the area of the smaller solid, we use the formula below
Where:
- a = Area of the smaller solid.
- A = Area of the larger solid
make a the subject of the equation
- a = (l²A)/L²................ Equation 2
From the question,
Given:
Substitute these values into equation 2
- a = (4²/9²)567
- a = 112 km²
Hence, the surface area of the smaller solid is 112 km².

Answer:
Composite area is 400+157=557
or 400 + 50pi
Step-by-step explanation:
First find the area of the square
A=s*s A= 20*20
Area of the square portion is 400
then find the area of the semicircle- we know the diameter of the circle is 20, so the radius is 10.
so
Composite area is 400+157=557
or 400 + 50pi
Answer: C
Step-by-step explanation:
Length = x+6
Width = 2(x+6)
Area = x+6*2x+12
= 2+72
All you have to do is length times with trust me
