Helppp 20 POINTS!!!The radius of a circle is 4 inches. Using the formula A ≈ 3r2, what is the approximate area of the circle?

1 answer:

5 0

Fyi area=pir^2 not 3r2
(oh, I see, you want to aprox pi=3, ok)

radius=4

3(4^2)=area
3(16)=area
48=area

answer is 48in^2

Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 35

Step 2: Solve for x hits

Substitute [BLF]: 35 = 0.15x - 1.5
Add 1.5 on both sides: 36.5 = 0.15x
Divide 0.15 on both sides: 243.333 = x
Rewrite: x = 243.333

Remember that this is a prediction. According to the best line of fit, we would need approximately ~243 to get 35 home runs.

A rectangle has an area of 84 square feet. the length is twice the width. draw a rectangle and draw a line dividing it in two to

algol13

The width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.

<h3>How to determine the dimensions</h3>

The formula for determining the area of a rectangle is expressed as;

Area = width × length

Given that;

Area = 84 square feet
length = 2w

Let's substitute into the formula

84 = w(2w)

84 = 2w²

Divide both sides by 2

84/ 2 = w²

42 = w²

Take square root of both sides

w = √42

w = 6.4 feet

Length = 2w = 2 × 6. 4 = 12. 96 meters

Thus, the width and length of the rectangle are 6.4 feet and 12. 96 meters respectively.
