7560.766
Step-by-step explanation:
The equation for the volume of a right cone is .
r = radius = 38/2 = 19cm
h = height = 20cm
Therefore:
Answer: A: 75°
Step-by-step explanation:
Here the angles of the given triangle are 70°, 35° and x
Since, the sum of all three angles of a triangle is 180°,
⇒ Option A is correct.
0.4x + 3.9 = 5.78
1. Subtraction property of equality:
Subtract 3.9 from both sides of the equal sign:
0.4x = 1.88
2. division property of equality:
Divide both sides of the equal sign by 0.4:
X = 4.7
