Circumference of a Circle Given Radius
Write the equation you would use to answer this question:
What is 45% of 68?
What is "X = 0.45(68)?"
Calculate the radius of a circle that has a value of Pi=3.14 and an area of 28.26 ft squared.
What is 3 ft?
Set up an equation to answer this question:
What percentage of 3000 is 333?
What is 3000(P) = 333
(Remember to move the decimal point over two places to the right after you find the quotient to change the decimal into a percentage.)
Set up an equation to answer this question:
92% is 128 of what number?
0.92 = 128N
The circumference of a circle is 97.3 inches. Find the radius.
What is 15.15 inches?
The circumference of a circle is 78.5 ft. What is the diameter?
What is 25 ft?
My new ear buds were originally $345 at the local electronics store. The bright green and white advertisement flyer stated, "Take 45% off the price of any pair of airbuds in the store!"
Use a percent equation with a decimal to answer the following question:
What was the price of the earbuds after the discount?
0.45 • 345 = Discount
Original price = $345.00
Discount - $155.25
What is $189.75?
What is 1.5?
I originally wanted a circular breakfast room with an area of 50.24 square feet. The builder firmly suggested using just half of a circle for the space to save $$ on the windows. I choose tile for the breakfast room and a cherry wood floor for the kitchen. To make the transition between the breakfast room and kitchen look smooth, I will need to buy a thin strip of wood to divide the kitchen from the breakfast room. How many feet of this thin strip will be needed for this transition piece?
What is 8 feet?
1. Find the radius: 50.24÷3.14 = 16
2. Find the square root of 16, which is 4.
3. Double the radius to find the diameter = 8.
I paid $32,892 for a beautiful used Honda Pilot, complete with leather seats and a moon roof! The original price was $55,000. What percent of the original price did I pay?
You must use a percentage equation to answer this question AND you must round to the nearest whole percent.
What is $32,892 = P• ($55,000)
P = 0.5980
Move decimal point to change to a percent:
I paid 60% of the original price for my new Honda.
