(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250
hope this helps

Answer:
A
Step-by-step explanation:
You don't know whether they're all 90 degrees because we don't know about AB and CD.
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>
