Answer:
18z
Step-by-step explanation:
The highest common factor of 54, 18 and 36 is 18
The highest common factor of z³, z and z² is z
The highest common factor of 54z³, 18z and 36z²
is therefore 18z
Answer:
324π in²
Step-by-step explanation:
The surface area of a sphere = 4πr² ( r is the radius )
Calculate r using the volume (V) formula
V = 
πr³
Here V = 972π , thus
πr³ = 972π ( divide both sides by π )
r³ = 972 ( multiply both sides by 3 to clear the fraction )
4r³ = 2916 ( divide both sides by 4 )
r³ = 729 ( take the cube root of both sides )
r = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
= 9
Thus
surface area = 4π × 9² = 4π × 81 = 324π in²
Answer:
A.12
Step-by-step explanation:
2×r-13 = 11
r + 2 = 14
11 + 14 = 25
699 is closet because as you subtract every number from 750, the smallest answer given is the closest to the number you started with.
