Answer:
792m^2
Step-by-step explanation:
Seperate your 2 rectangles
Large one is 18*30
Small one (60-18)*6
18*30 = 540m^2
42*6=252m^2
Answer:
Step-by-step explanation:
Answer:
The length of the wire is 76.19 m.
Step-by-step explanation:
It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
It means base of the right angled triangle is 40 m.
The wire makes an angle of 58deg 20min with the ground.
1 degree = 60 min
Using this conversion convert the given angle in degree.

In a right angled triangle





Therefore the length of the wire is 76.19 m.
Answer:
You need to be specific on which is the length, height and width. Making the most basic assumption I would have to assume the answer is 228
Step-by-step explanation:
Formula for the surface area of a rectangular prism is A=2(wl+hl+hw)
A = 2 x (9 x 6 + 4 x 6 + 4 x 9)
A = 2 x (54 + 24 + 36)
A = 2 (114)
A = 228
C=2 pie r
(example circumference=28)
28=2 x 22\7 x r
28=6.29r
then divide both sides by 6.29
28\6.29=4.45
r=4.45
