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
Sorry for the delay but I answered your question and the answer is -6xsquare +11x-4
(70x10)+(6x1)+(4x1/10)+(2x1/100)+(9x1/1000)
Answer:
The larger angle is 54°
Step-by-step explanation:
Given
Let the angles be: θ and α where
θ > α
Sum = 72
α : θ = 1 : 3
Required
Determine the larger angle
First, we get the proportion of the larger angle (from the ratio)
The sum of the ratio is 1 + 3 = 4
So, the proportion of the larger angle is ¾.
Its value is then calculated as:.
θ = Proportion * Sum
θ = ¾ * 72°
θ = 3 * 18°
θ = 54°
I think is 4000 because when it's sad 1 singnificant figure you have to round the first name which 4
