Answer:C.
Step-by-step explanation:
Answer:
14.48 ft
Step-by-step explanation:
The relation between the location of the focus (c), the vertex on the major axis (a) and the vertex on the minor axis (b) with respect the center is:
b² = a² - c²
From the question:
c = 4 ft
a= 30/2 = 15 ft
Replacing into the equation:
b² = 15² - 4²
b = √209
b = 14.48 ft
So, he should build the whisper chamber at 14.48 ft out from the center along the minor axis
Answer:
x = -28
Step-by-step explanation:
x-(-5) = x + 5
x + 5 = -23
-23 - 5 = -28
x = -28
Answer:
D. 314 m²
Step-by-step explanation:
Area of circle= π r²
Radius = r = 10 meter
By putting radius in formula we get
area = 314.159 m² and nearest square meter is 314 m²
