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 it's 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 :

2. Sphere

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

volume formula :

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 :

Solution

1. Cylinder

r = 3.5 m

h = 8 m

volume formula :

V = 3.14 x 3.5² x 8

V = 307.72 m³

2. Sphere

r = 20 dm = 2 m

volume formula :

3. Cones

r = 7 m

h = 20 m

volume formula :

4. Pyramid

L = 3.5 in = 0,0889 m

W = 1.5 in = 0,0381 m

H = 4 in = 0,1016 m

volume formula :
