Answer = C
That would be A I believe
<h2>Answer: Step-by-step explanation:
B - should be your answer
The equation you need to solve this is v = πr²h
Volume = pi x radius squared x height Your radius is half of your diameter Half of 12 meters is 6 meters 6 meters is your radius Your height is 10 meters
Put your values in place in the equation
Volume = π x 6² x 10 Raise 6 to the power of 2
π x 36 x 10 Move 36 to the left of π Multiply 10 by 36 360π m³</h2>
Answer:
40
Step-by-step explanation:
To find how much gasoline is needed for 480 kilometers, we will need to find how much is needed per kilometers:
13 liters is used for 156 kilometers
156/13 = 12 so 1 liter gasoline is spent per 12 kilometers
So for 480 kilometers we would need 40 liter gasoline because
480/12 = 40
Answer:
AB ≈ 15.7 cm, BC ≈ 18.7 cm
Step-by-step explanation:
(1)
Using the Cosine rule in Δ ABD
AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )
= 153.76 + 272.25 - (409.2 cos64° )
= 426.01 - 179.38
= 246.63 ( take the square root of both sides )
AB = ≈ 15.7 cm ( to 1 dec. place )
(2)
Calculate ∠ BCD in Δ BCD
∠ BCD = 180° - (53 + 95)° ← angle sum in triangle
∠ BCD = 180° - 148° = 32°
Using the Sine rule in Δ BCD
= = ( cross- multiply )
BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )
BC = ≈ 18.7 cm ( to 1 dec. place )
