For #4, we know V = lwh
We have the values
5184 = 2(18)h
Solve for h
5184 = 36h
144 = h.

for # 3:
we know A = pi r^2
We have 
A = 3.14 * 6^2
A = 3.14 * 36
A = 113.04

for #2:
We know C = 2pi *r
C = 2(3.14)(14)
C = 28(3.14)
C = 87.92

for #1:
C = 2pi * r
C = 2(3.14)(26.3/2)
C = 2(3.14)(13.15)
C = 26.3(3.14)
C = 82.582

Answer:

1080cm²

Step-by-step explanation:

surface area=sum of the area of all the shapes

area of triangle=1/2*base*height

1/2*24*10=120*2(because there are two triangles)=240cm²

10*14=140cm²

24*14=336cm²

Area of slanting figure=26*14=364cm²

add all the results

240+140+336+364=1080cm²

We can use the Pythagorean theorem to solve for the perimeter of the kite.

a² + b² = c²

3² + 4² = UV²

9 + 16 = UV²

25 = UV²

√25 = √UV²

5 = UV

In the kite, adjacent sides are the same so UV = VW

3² + 9² = UX²

9 + 81 = UX²

90 = UX²

√90 = √UX²

9.49 ≈ UX or 3√10 ≈ UX

Now, add to find the perimeter.

5 + 5 + 9.49 + 9.49 or 5 + 5 + 3√10 + 3√10

28.98 or 10 + 6√10

Therefore, the perimeter is approximately 28.98 or 10 + 6√10

Best of Luck!
