The area of the cross section of a sphere at the largest point is 100π square miles. what is the total surface area of this sphere? leave your answers in terms of π.

The cross-section of a sphere  is a circle . The  area of a circle can be calculated by the formula A= Where r is the radius of the circle.

Given :

Solving for r we have:

Or r= 10.

The area of a sphere is calculated by the formula :

Substituting r value we have:

SA=

The total surface area of this sphere is 400π .

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
