Using the Quadratic Function, Such Means x = - b + or - the square root of - 4 a c over 2 a.
After you do it you would get the answer :
Hoped I Helped, Have A Great Day :)
Answer:
for me the answer was c not sure if you will get it correct but again the answer for me was C
Step-by-step explanation:
First, determine the circumference (C) of the circle, the equation,
C = 2πr
Substituting the value or the radius,
C = 2π ( 4) = 8π
The arc length is the product of the circumference and the ratio between the subtended angle and 360. The mathematical expression is already,
S = (8π) x (72 / 360) = 0.8π
Thus, the arc is 0.80π.
Answer:
B) 65 sq in
Step-by-step explanation:
SA = area of base + 1/2(perimeter of base)(slant height)
= 5² + 1/2(20)(4)
= 25 + 40
