Which number is not written in scientific notation

Mariana [72]

Answer:

The rule for scientific notation is that the coefficient has to be between 1 and less than 10. This means there is only one digit in front of the decimal. 15x10^20 should be written as 1.5x10^21 to follow the rule.

vivado [14]

Answer:

hello the figure related to your question is missing attached below is the missing figure

answer : 157.08 m^2

Step-by-step explanation:

Calculate the area of the shaded area

= Area of the large circle - Areas of the small circles

= (( $\frac{\pi }{4}$ ) * D^2) - 2( ( $\frac{\pi }{4}$ ) * d^2 ) given that the small circles are congruent

= (( $\frac{\pi }{4}$ ) * 20^2 ) - 2 ( ( $\frac{\pi }{4}$ ) * 10^2 )

= 314.16 - 157.08

= 157.08 m^2
