Answer:

A= 13.8474

Step-by-step explanation:

The formula for the area of a circle is A= πr^2 (pi times r, or radius, squared).

So if you insert the values into the formula you have....

A= 3.14(2.1 cm)^2

You can use a calculator from there to get....

A= 13.8474

9 less than the sum of x and 5

saw5 [17]

Answer:

Given the statement:

9 less than the sum of x and 5

"Sum of x and 5" means $x+5$

" $\text{less than}$ " means subtract

then;

the statement 9 less than the sum of x and 5 becomes;

⇒ $(x+5) - 9$

⇒ $x+5-9 = x-4$

Therefore, the expression for the given statement is $(x+5) - 9$

B) Make b the subject of the formula a = 4 - 3b

Ira Lisetskai [31]

A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
