Hey there!
Formula: πr^2
r = radius
pi = 3.1415926535898 (but we can say it approximately equals 3.14)
Your equation (3.14)(4.2)^2 = answer
4.2^2 = 4.2 × 4.2 = 17.64
New equation: 17.64 × 3.14 = 55.3896
We round our answer to the nearest tenth
Answer: 55.4 ☑️
Good luck on your assignment and enjoy your day!

Answer:
The percent error of Heather's calculation is <u>8%</u>.
Step-by-step explanation:
Given:
Heather measures the temperature of her coffee to be 133.4 degrees fahrenheit. It is actually 145 degrees fahrenheit.
Now, to find the percent error of Heather's calculation.
The temperature of coffee Heather measures = 133.4° F.
Coffee's actual temperature = 145° F.
So, to get the measurement in error we subtract the temperature of coffee Heather measures from coffee's actual temperature:
Now, to get the percent error:
Therefore, the percent error of Heather's calculation is 8%.
You have to use your area equations.like basex height
Answer:
The volume of a rectangular prism is given as
Volume = Length × Width × Height
Step-by-step explanation:
The area of the base of the rectangular prism is given as the product of the length and the width that is
Area of base = Length, L × Width, W
Which is L·W square units, to transform the square units into cubic units, we will multiply the base area by the height as follows
Area of base × Height, H = Length, L × Width, W × Height, H cubic units
or L·W·H cubic units = Volume of a rectangular prism.
