Answer:
hello :
Step-by-step explanation:
the area of a circle is : A = π r² r : the radius
A = π (6)² = 36π (ft)² ........( answer : C)
Substitute x with its value, -14
y=1/2 (-14)
y= -14/2
y= -7
Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
Answer:
the correct answer is
D. 80 ft^3
vol. of pyramid = (l× w × h)/3
= (6×8×5)/3
= 80 ft^3
