Answer: 9.3 ×
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
In this case, we can write 93,000,000 as 9.3000000 and notice that there is only one digit to the left of the decimal point.
Next, we count the number of places the decimal point would need to move to get back to the original number which is 93,000,000.
Since we will need to move the decimal point seven places to the left, we have an exponent of positive 7. Our exponent will be positive because we need to move the decimal point seven places to the right. Now, we can write our number in scientific notation.

Hi there!
Using the equation for the area of a circle, we can simply substitute pi with its numerical value of 3.14 and r with the radius given.
1.) Area = (3.14)(6cm)² = 113.0 cm²
2.) Area = (3.14)(28in)² = 2461.8 in²
3.) To find radius, first we must divide the diameter in half. So, 11/2 = 5.5 ft
Area = (3.14)(5.5ft)² = 95 ft²
4.) Similar to 3, to find radius, first we must divide the diameter in half. So, 10.5/2 = 5.25 in
Area = (3.14)(5.25in)² = 86.5 in²
5.) Area = (3.14)(6.3mm)² = 124.6 mm²
6.) Area = (3.14)(3
yd)² = 33.2 yd²
