Question

the total surface area of a cone with hemispherical ice cream is 858 cm². slant height of a cone off the radius is 7cm and the height is 24 cm is 25cm. the curved surface area of hemisphere is the base radius is 7 cm is 308 cm². can you please explain this with steps.​

Answer 1

Answer:

Explanation given below

Step-by-step explanation:

Given, r = 7cm
h = 24cm
l = 25cm
CSA of cone = πrl = 22/7*7*25 = 550cm^2
CSA of hemisphere = 2πr^2 = 2*22/7*7*7 = 154*2 = 308cm^2
TSA of Ice Cream = CSA of cone+CSA of hemisphere =                   550cm^2+308cm^2 = 858cm^2

Have a good day ^^

Answer 2

Answer:

Explanation given below

Step-by-step explanation:

Given, r = 7cm

h = 24cm

l = 25cm

CSA of cone = πrl = 22/7*7*25 = 550cm^2

CSA of hemisphere = 2πr^2 = 2*22/7*7*7 = 154*2 = 308cm^2

TSA of Ice Cream = CSA of cone+CSA of hemisphere =                   550cm^2+308cm^2 = 858cm^2
