Answer» R1=d/2=60/2=30cm. h1=30cm R2=31cm. h2=60cm r3=? h3=10cm V1+v2=V3 π r1^2 h+π r2^2 h=π r3^2 h3 π(r1^2 h1+r2^2 h2)=π r3^2 h3 r1^2 h1+r2^2 h2=r3^2 h (30)^2 (30)+(31)^2 (60)=r3^2 (10) 27000+57660/10=r3^2 84660/10=r3^2 r3^2=8466 r3=√8466 r3=92.01cm d3=2r3 d3=2(92.01) d3=184.02cm mark me as BRAINLIEST |
