Answer:

Geometry

Spatial figures are 3-dimensional shapes that can be measured in Cartesian coordinates on the x-axis, y-axis, and z-axis. . With this 3-dimensional shape, it causes the figures to have volume and surface area. Every shape has a formula whether its volume or surface area.

Further explanation

there are several shapes in the question

1. Cylinder

A cylinder is a geometric figure consisting of 3 sides, namely 2 equal circles and 1 quadrilateral that surrounds the two circles.

volume formula :

\tt V=\pi.r^2.hV=π.r

2. Sphere

A sphere is a geometric figure composed of an infinite number of circles.

volume formula :

\tt V=\dfrac{4}{3}\pi r^3V=

3. Cones

A cone is a geometric figure consisting of a circle and a curved plane.

volume formula :

4. Pyramid

A quadrilateral pyramid is a shape that has a rectangular base

volume formula :

\tt V=\dfrac{1}{3}.L.W.hV=

Solution

1. V cylinder = 78 cm³

\begin{gathered}\tt V~cylinder=\pi r^2.h=78\\\\V~cone=\dfrac{1}{3}\pi r^2.h=\dfrac{1}{3}\times 78=26~cm^3\end{gathered}

V cylinder=πr

2. V pyramid = 36 cm³

\begin{gathered}\tt V~prism=l.w.h=3\times (\dfrac{1}{3}l.w.h.)=3\times V~pyramid\\\\V~prism=3\times 36=108~cm^3\end{gathered}

V prism=l.w.h=3×(

l.w.h.)=3×V pyramid

V prism=3×36=108 cm

3. V cylinder = 198 cm³

The volume of a sphere is two-thirds the volume of a cylinder.

\begin{gathered}\tt V~cylinder=\pi r^2.h=198\\\\V~sphere=\dfrac{2}{3}\pi r^2.h=\dfrac{2}{3}\times 198=132~cm^3\end{gathered}

4. V sphere = 67.53 198 cm³

The volume of a sphere is two-thirds the volume of a cylinder.

\begin{gathered}\tt V~sphere=\dfrac{2}{3}.V~cylinder\\\\V~cylinder=\dfrac{3}{2}\times V~sphere\\\\V~cylinder=\dfrac{3}{2}\times 67.53=101.295~cm^3\end{gathered}

5. V pyramid = 45.53 cm³

\begin{gathered}\tt V~prism=l.w.h=3\times (\dfrac{1}{3}l.w.h.)=3\times V~pyramid\\\\V~prism=3\times 45.53=136.59~cm^3\end{gathered}
