Question

Please Help! WILL GIVE MEDAL!!
Cameron is replacing the roof on a gazebo. The roof is in the shape of a cone with an open bottom. The radius is 7 feet and the slant height is twelve feet. What is the lateral area of the roof? Use three point one four for pi.

two hundred sixty-three point seven six square feet

three hundred seventy-six point eight square feet

seven hundred fifteen point nine two square feet

eight hundred seventy-nine point two square feet

Answer 1

lateral area = pi*r*s where s is the length of the slope of the cone

pi*r*s = pi*10*6 = 60*pi = 188.4956 ft^2
this is what i found .

Answer 2

That's not an option though:(

Answer 3

Ok......so
The formula is πrh.

Where:

π = 3.14

r = Radius

h = Height...Hope you can take it from here?

Answer 4

so 3.14 times 7 times 12= 263.76... thanks!!!!

Answer 5

Let me write for you anyways:
πrh

(3.14)(7)(10)

(It gives you the diameter, and the radius is half the diameter which gives us 7)

(21.98)(10)

219.8
