Peter is wants to lose weight. he is105kg. his aim is to lose 500 g per week. if he managed this, how many weeks will it be until he is 90kg?

105 - 90 = 15kg

500g = 1/2 kg

Peter is 15kg overweight.

15 x 2 = 30

It will take him 30 weeks for this.

30 weeks

Step-by-step explanation:

Subtract 90 kilograms from 105 kilograms. (15 kilograms)

Convert 500 grams into kilograms. 500 grams is only half of 1000 grams which is the amount of grams you need to make up one kilogram, so we know we won't have a whole kilogram. You should come up with 0.5 grams as your answer once you have converted 500 grams into a kilogram.

Multiply 15 x 0.5 and you should get 30.

It will take Peter 30 weeks.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
