Answer:
9
Step-by-step explanation:
Rewrite the whole numbers as multiplication.
(*excluding parentheses)
I could be wrong but i believe it's six
To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr. We need to solve for r.
23 = 2πr
r=3.66
The calculation for surface area is <span>A = 4πr^2.
</span>A = 4<span>π(3.66)^2
Solve for A.
A= 168 cm^2.</span>
<span>6y-5=-3(2y+1)
6y - 5 = -6y - 3
12y = -3 + 5
12y = 2
y = 2/12
y = 1/6</span>
