The Y is the diameter

Find Y

Area of the circle

Answer 1

Answer:

Answer:

Y = 22.56 cm

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

${r}^(2) = (400)/(\pi)$

Find the square root of both sides

$r = \sqrt{ (400)/(\pi) }$

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

Y = 22.56 cm

Hope this helps you

A worker at a mill is loading 5 pound bags of flour into boxes to deliver to a local warehouse. Each box holds 16 bags of flour. If the warehouse orders 4 tons of flour how many boxes are needed to fulfill the order ?

Answers

Answer:

100

Step-by-step explanation:

volume of 16 bags of flour: 16 x 5 = 80 pounds

We know that: 1 ton = 2,000 pounds -> 4 tons = 2,000 x 4 = 8,000

So we need: 8,000 : 80 = 100 boxes to fulfill the order
