STEP 1: find base area AB
To find base area AB use formula:
AB=r2⋅πAfter substituting r=9.6cm we have:
AB=(9.6cm)2⋅π AB=92.16cm2⋅π STEP 2: find Curved Surface Area CSA
To find Curved Surface Area CSA use formula:
A=AB+CSA After substituting A=1178.6304cm and AB=92.16πcm2 we have:
1178.6304cm=92.16πcm2+CSA CSA=1178.6304cm−92.16cm2 CSA=1086.4704cm STEP 3: find slant height l
To find slant height l use formula:
CSA=l⋅r⋅πAfter substituting CSA=1086.4704cm and r=9.6cm we have:
1086.4704cm=9.6cm⋅l⋅πl=9.6cmπ1086.4704cml≈36.0243
