Answer:
the radius is about 14.47 ft
Step-by-step explanation:
658=pi*r^2 Given
658=3.14*r^2 Substitution
209.55=r^2 Division property of equality
√209.55=√r^2 square root property of equality
the radius is about 14.47 ft
Answer:
7.31 and 0.685
Step-by-step explanation:
x^2 -8x +5 = 0
use the quadratic formula
- (-8) + √(-8^2 -4(1)(5) / 2(1(
(8 + √(64 -20))/2
(8+√44)/2
8+6.63 / 2
14.63/2= 7.31
+7.31
(8- √44)/2 = 0.685
