Answer:

Step-by-step explanation:

Volume = length * width * height

= (x + 1) *x *(3x + 5)

Multiply (x +1) and x

= (x*x + x*1) * (3x +5)

= ( x² + x) * (3x + 5)

= x²*(3x +5 ) + x(3x +5)

=x²*3x + x²*5 + x*3x + x*5

= 3x³ + 5x² + 3x² + 5x

= 3x³ + 8x² + 5x

I need to know the answer to the question with the circle

___________________________

◆ AREA RELATED TO CIRCLES ◆ ___________________________

As shown in the figure ,

Radius of circle = 5 cm

Side of square = 2 × (Radius of inscribed circle)

Side of square = 2 × 5 cm

Side of square = 10 cm = a

___________________________

Now ,
Area of shaded region = (Area of square) - ( Area of inscribed circle )

Area of shaded region =
${a}^{2} - \pi {r}^{2}$

Area of shaded region =
${10}^{2} - \frac{22}{7} \times {5}^{2}$

Area of shaded region = 100 - 78.571

$= 21.428 \: ans.$
