Question

ans my que plz tell me ans if you are a genius​

Answer 1

Answer:

Step-by-step explanation:

Volume of toy =V of cone +V of hemisphere

=1/3 πr²h  +2/3 πr³

=1/3 ×22/7×4×4×4  +2/3 ×22/7×4×4×4

=67.05 +134.09

=201.14 cm³

Volume of cube = a³

8×8×8 =512 cm³

differrence =V of cube  - V of toy

=512 -201.14 =310.86 cm³

Total surface area of toy = S.A of cone + S.A of hemisphere

=πrl +2πr²  = 22/7 ×4×4√2  +2×22/7 ×4×4

=71.09 +100.57 =171.66 cm²

NOTE:

slant height(l) =√h²+√r² =√4² +√4²  =√32 =4√2

Answer 2

Answer:

(50.24-25.12)cm^

=25.12cm^
