Answer:
72 / 5
Step-by-step explanation:
( 12 / 5 ) + ( 6 / 5 )
= ( 12 + 6 ) / 5
= 18 / 5
[ ( 12 / 5 ) + ( 6 / 5 ) ] / ( 1 / 4 )
= ( 18 / 5 ) / ( 1 / 4 )
= ( 18 x 4 ) / 5
= 72 / 5
1. 4/5 - 2/15 = 2/3
2. 4/7 - 2/8 9/28
Answer:
cylinder surface area = 201.06in²
surface area of cone = 56.56in.²
Step-by-step explanation:
cylinder surface area formula = 2πrh + 2πr²
refer the pic
cone surface area formula = πr ( r + √h² + r² )
refer the sec pic
surface area of the solid
= ( 201.06 + 56.56 ) in.²
= 257.62in.²
= 258in.²
