Answer:

3.14 or pi

Step-by-step explanation:

the area of a circle = pi * r^{2} where r is the radius of the circle

this is 1/4 of the circle, so it would be 1/4 (pi * r²)

it shows that the radius is 2, so you have

1/4 ( pi * 2²)

= 1/4 ( pi * 4 )

= 1/4 (3.14 * 4)

= 3.14 units²

The number a exceeds the number b by 50 percent. By what percent is the number b smaller than the number a?
Julli [10]
50%, because to exceed is to be larger than, so if A is larger than B by 50%, then that means that B is 50% smaller than A.

The quotient below is shown without the decimal point. Use number sense to place the decimal point correctly.
katrin2010 [14]

Answer:

35.8

Step-by-step explanation:

                \frac{340.1}{9.5}  = 358

 We know that our answer can never be greater than 358 since the dividend

is 340.1 and the divisor is 9.5;

  Also,

  Both values are to one decimal places and we can use this to solve the problem;

  9 can divide 340 in about 37 place with a remainder of 7,

    So, it is appropriate to make the solution 35.8

5x-3=19? Answer for Brainliest
vampirchik [111]

Answer:

x = 4.4

Step-by-step explanation:

I'm going to assume you want to solve for x so here we go.

You need to work backwards for this equation, and whatever you do to the LHS, you do to the RHS.

First, you need to remove the minus 3, which means that on both sides, you add 3. Adding three on the LHS makes the -3 disappear, and adding 3 on the RHS makes the 19 go to a 22.

Your equation is now 5x=22.

Since 5x means 5 × x, to get rid of it, you need to divide 5x by 5. Doing it to the LHS will make the five disappear, and doing it to the RHS will make it go to 22 ÷ 5 which equals 4.4

Therefore, x = 4.4
