Answer:
£12 per hour
Step-by-step explanation:
7 × 5 = 35 hours
35 h : 420
1 h : x
x = 420×1 / 35
= £12 per hour
Answer:
F 904.32in ^3
Step-by-step explanation:
first use find the radius, which is always half the diameter, in this case 6.
then use the formula, knowing the radius is 6
![v = 4 \div 3 \pi {r}^{3}](https://tex.z-dn.net/?f=v%20%3D%204%20%5Cdiv%203%20%5Cpi%20%7Br%7D%5E%7B3%7D%20)
the cube the radius
![{6}^{3} = 216](https://tex.z-dn.net/?f=%20%20%7B6%7D%5E%7B3%7D%20%20%3D%20216)
multiple radius by 4/3
![(4 \div 3)216 = 288](https://tex.z-dn.net/?f=%284%20%5Cdiv%203%29216%20%3D%20288)
then multiply by pi
![\pi \times 288 = 904](https://tex.z-dn.net/?f=%5Cpi%20%5Ctimes%20288%20%20%3D%20904)
