Answer:
Finding volume:
2^2 = 4
4 x 3.14 = 12.56
12.56 x 8(height) = 100.48
100.48 divided by 3 ( x 1/3 ) = around 33.49 in3 is your answer.
If the options dont give you 33.49 just go by 33.51 cubic meters.
The equation for the blue graph is D
Each drawing they are just adding another row to the right so for the 7th picture, there would be 28 dots. Another explanation is that they are just adding the same number of dots for each number it is. For example, for the 5th image, they added 5 dots to the previous image and so on.
Answer:
c = 27.9
B = 62.13°
C = 89.90°
Step-by-step explanation:
We are given the following values:
A= 121.59°, a = 27.9 cm, b = 52.6 cm
a) Finding side c
We would use Pythagoras Theorem
c² = a² + b²
c = √(a² + b²)
c = √(27.9² + 52.6²)
c = 59.54cm
≈ Approximately = 59.5cm
b) Finding B
We would be using Cosine rule to find Angle B
Cos B = a² + b² - c²/2ab
B = arc cos ( a² + c² - b²/2ac)
B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)
B = 62.13268°
B = 62.13°
c) Finding C
We would be using Cosine rule to find Angle C
Cos C = a² + b² - c²/2ab
C = arc cos ( a² + b² - c²/2ab)
C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)
C = 89.9°
