Answer:
374cm²
Step-by-step explanation:
Total Surface area of a cone = Total area to be polished
Total Surface area of a cone = Total area to be polished r = 7cm
Total Surface area of a cone = Total area to be polished r = 7cml = 10cm
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l = 22/7 ×7 ( 7+10)
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l = 22/7 ×7 ( 7+10){ 7 on the denominator and 7 on the numerator will be cancelled}
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l = 22/7 ×7 ( 7+10){ 7 on the denominator and 7 on the numerator will be cancelled} then
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l = 22/7 ×7 ( 7+10){ 7 on the denominator and 7 on the numerator will be cancelled} then = 22×17
Total Surface area of a cone = Total area to be polished r = 7cml = 10cmTSA of the cone = pie × r( r+l = 22/7 ×7 ( 7+10){ 7 on the denominator and 7 on the numerator will be cancelled} then = 22×17= 374cm²
therefore :- total area to be polished is 374cm²
therefore :- total area to be polished is 374cm²Here your answer mark as the brainliest
