The slope of the linear regression equation y = 61. 93x - 1. 79 is attached with the response.
<h3>What is linear regression?</h3>
Linear regression is the most primary and generally used predictive research. Regression calculations are utilised to represent data and to describe the association.
The slope of the linear regression equation represented in the graph is the straight-line cutting the intercepts on the y axis at 1.79.

so obviously first of all find three sherical objects or balls of varioius sizes to make it easier get a large medium and small sized. 
then on scratch paper sketch those objects (im assuming by the looks of it you would trace them if not just draw them then take measuring tape or a ruler across to measure said object) now you arent told what units to measure in but id assume to stick with one unit either inches or cm
mesure the length across which is the circumference
now you would just have to do your calculations by finding the radius and volume and surface area
remember volume is (*units) cubed and suface area is (*units) sqared

R=16
J=32
20+40(which is 20×2)=60
20-4=16
