Question

Snow cones!



An image of an ice cream cone is shown below.



The slant height of the cone itself is 3.5 inches, and the radius of the ice cream scoop on top is 0.75 inches. What is the approximate surface area of the entire ice cream cone with the scoop of ice cream?
Answer
3.8π square inches
3.2π square inches
4.3π square inches
5.4π square inches

Answer 1

So figure out what equations youll need to use

Answer 2

what solids are involved?

Answer 3

well to find the lateral area of a cone we use equation pi*r*s and for sphere it's 4 pi*r^2. Since there is only half a circle i guess we divide by 2 when we get the surface area of the half sphere?

Answer 4

that should work yup :)

Answer 5

so after i get the LA of the cone and the SA of the half sphere now what?

Answer 6

add em

Answer 7

erm i get 11.775

Answer 8

divide by pi

Answer 9

I get 3.75pi with that I dont know if you rounded to get 11.775?

Answer 10

no

Answer 11

I got the surface area of the half sphere then i got the answer if it was a whole sphere and divided it by 2

Answer 12

K hold on ill do both equations myself

Answer 13

ok

Answer 14

So pi*r*H

Answer 15

what is the height of the cone

Answer 16

3.5

Answer 17

how do you get that
