3. Calcola l'area del rettangolo \( A B C D \) sapendo che \( B D=35 \mathrm{~cm} \) e \( C H=16,8 \mathrm{~cm} \). \( \quad\left[588 \mathrm{~cm}^{2}\right] \)

Exploration A sugar cube has a volume of about 1 cubic centimeter. Estimgte the size of a box you would need to hold \( 1,000,000 \) sugar cubes?

If the height of a cylinder is doubled while keeping the radius constant, how does that affect its volume?

Write the corresponding parts not given for the congruent triangles. \( \angle B=90^{\circ} \) and \( \angle \mathrm{T}=90^{\circ} \) \( \mathrm{CB}=\mathrm{UT} \) \( \mathrm{AB}=\mathrm{ST} \)

Qual é a fórmula para calcular a área de um círculo?
