Answer:
5.6 units
Step-by-step explanation:

Given that the area of the circle is 31.36π,
31.36π= πr²
Divide both sides by π:
31.36= r²
r²= 31.36
Square root both sides:

r= 5.6 units
GCF = 4
factors of 44 are : 1, 2, 4, 11, 22, 44
factors of 32 are : 1, 2, 4, 8, 16, 32
common factors are : 1, 2, 4
GCF = 4
Answer:
tan 60 = opp/adj = a/10
a = 10×tan60 = (10 yd)×[(√3/2)/(1/2)]
= 17.3 yd
= 10√3 yd
I am assuming the -3 is an exponent.
y⁻³ and 5⁻³
If the exponent is a negative number, it simply means that the number is a denominator with 1 as the numerator.
y⁻³ is 1/y³
5⁻³ is 1/5³ = 1/125
The number is still raised to its exponential power but its placement is different.
5³ would be 125 or 125/1. It would be the numerator with 1 as the denominator.
I need to know which question it is though
