The change in grandpa Ernie's height each year is equal to 0.6cm.
As given in the question,
Number of years for which grandpa's height is shrinking = 4 years
The total decrease in height after four years is equal to 2.4cm.
Let x represents the decrease in height each year
The required equation to calculate decrease in height each year is given by:
4x = 2.4
⇒ x= 2.4 /4
⇒x = 0.6cm
Therefore, the change in grandpa Ernie's height each year is equal to 0.6cm.
The complete question is :

Answer:
22.8
Step-by-step explanation:
The circumcenter is equidistant from all the vertices of the triangle: PV = RV. There are enough dimensions given to let us find RV from the Pythagorean theorem.
RV² = RS² +SV²
RV² = 11² +20² = 521
RV = PV = √521 ≈ 22.8
