Question

For figure shown, match the column

Answer 1

curved surface area of hemisphere $=2\left(\pi \right)r^2=2\ast 3.14\ast (1.75{)}^2=19.2325$
Option 2
Height of cone $=5-1.75=3.25$
option 1
slant height $=\left(\sqrt{r^2+h^2}\right)=\left(\sqrt{(1.75{)}^2+(3.25{)}^2}\right)=3.7$
option 3
surface area of top $=2\left(\pi \right)r^2+\left(\pi \right)rl=2\ast 3.14\ast 1.75\ast 1.75+3.14\ast 1.75\ast 3.7=39.6$
option 4
