Answer:
13260 square inches
Step-by-step explanation:
In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
The formula to solve the above question is
1/2absinθ
a = 100 inches
b = 740 inches
θ = 159°
The area of the triangle =
1/2 × 100 × 740 × sin 159°
= 13259.61 square inches
Approximately = 13260 square inches
Therefore, the area of DEF = 13260 square inches
A) a bench --- C=2πr, if r=π, then C=2π²=19.74,
if you need to use π=3.14, then C=19.72 ft
cover ---- area =πr²=π³=31.01 ft²
if you need to use π=3.14, then A=30.96 ft²
B) R=2.5r
C=2πR, if R=2.5π, then C=2*2.5π²=5π²=49.35 ft
if you need to use π=3.14, then C=49.30 ft
how much longer = 49.35 -19.74=29.61 ft
A similar triangle means it is of a diferent size, but the sides or angles are proportionaly the same.
Use the rule of 3 on each number, to find the equivalent sides:
65 - 39
60 - x
(60 * 39) / 65
2340 / 65
36cm
60 - 36
25 - x
(25*36) / 60
900 / 60
15cm
Original triangle: 65, 60, 25
Similar triangle: 39, 36, 15
