Answer:
7.280 k
Step-by-step explanation:
Given that 1 g = 0.001 k
If he uses 520 grams of flour each day for 2 weeks, since there are 7 days in a week, the total weight of flour used in two weeks
= 520 g * 2 * 7
= 7280 g
In kilograms
Since
1 g = 0.001 k
7280 g = 7280/1 * 0.001 k
= 7.280 k
Answer:
The volume of cone v= 113.04 cm³.
Step-by-step explanation:
Formula used to find volume of cone is:

where r is the radius and h is the height of cone.
In the given question we are given:
height h= 6 cm
diameter d= 6 cm
We know radius r = d/2 = 6/2 = 3 cm
so, volume will be:



So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm
