She should add 48 ounces of of seltzer water because it will allow at least 10 servings. 32 ounces would only be enough to make 8.88 servings
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>
-3b+2 will be first. -3b+2= 5b
now, 6b+2b= 8b 8b+5b= 13b 13b + 5b = 18b+2 = 20b. Idk what the last 2 is but I'm assuming add it. so. 20b is my answer..
