Question

Find the area of the irregular figure (use 3.14 for pi). Show your work. Round to the nearest tenth.

Answer 1

area of the tip of cone is half a circle
(pi r^2)/2 and r is half of diameter
the area of botom is 2 triangles that are same size
base*r again r is half of diameter

and the total area is
half the circle + area of bottom.

Answer 2

Should the final answer be 26.39? Triangle = 8.64 Semi circle = 17.75?

Answer 3

4.8*(3.6*(1/2))+3.14*(3.6*(1/2))^2
18.81

Answer 4

could be wrong tho
4.8*(3.6*(1/2))+3.14*(3.6*(1/2))^2
( ) the 2 triangles
+( ) the circle oh wait i forget 2 half it you are right

Answer 5

4.8*(3.6*(1/2))+1/2*(3.14*(3.6*(1/2))^2) = 13.73

Answer 6

I my anwser or what should the final anser be?

Answer 7

I get 13.73

Answer 8

A = (1/2)bh + (1/2)(pi)r^2
A = (1/2)(3.6)(4.8) + (1/2)(3.14)(3.6/2)^2
A = 8.64 + 5.09 = 13.73
Round off to nearest tenth:
A = 13.7
timo is right

Answer 9

ooh :) i am right
