The area of a circle is 78.5 square yards. find the radius to the nearest whole using 3.14 for pi ( a = nr2)

Area = 78.5 yd²

πr² = 78.5

3.14r² = 78.5

r² = 25

r = 5

5 yds

Step-by-step explanation:

The formula for the area of a circle is expressed as

Area = πr^2

Where r represents the radius of the circle

π is a constant whose value is 3.14

The area of the given circle is 78.5 square yards. To determine the radius of the circle,

πrr^2 = 78.5

3.14πr^2 = 78.5

Dividing the left hand side ofbthe equation and the right hand side of the equation by 3.14. It becomes

r^2 = 78.5/3.14 = 25

Taking square root of both sides of the equation,

r = √25 = 5 yards

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
