HELP! the diagram shows a solid made by joining a solid hemisphere to a solid circular cone. the centre of the plane face of the cone coincides with the centre of the plane face of the hemisphere. the radius of the hemisphere is 3 cm. the radius of the base of the cone is 3 cm. the volume of the solid is 30 pi cm3. work out the total surface area of the solid. give your answer as a multiple of pi.

Not entirely sure but entire negative number set? -1 -2 -3 -4 so on i have no idea

Just add 10+3m the m means the roman numeral m is often used to indicate one thousand, and mm is used to indicate one million. for example, an expense of $60,000 might appear as $60m. sales of $3,000,000 might be written as $3mm. internet advertisers are familiar with cpm which is the cost per thousand impressions. so 10+3m= 300,000,010hope this and if it does can i have brainlest? if not tell me what i did wrong but i’m pretty sure i am right.
