Answer:

20.25 m²

Step-by-step explanation:

the area (A) and circumference (C) of a circle are calculated using the formulae

C = 2πr and A = πr² ( where r is the radius )

calculate the radius using the formula for circumference

2πr = 9π ( divide both sides by 2π )

r = \frac{9\pi }{2\pi } = \frac{9}{2} = 4.5, hence

A = π × 4.5² = 20.25π m²

Drag each tile to the correct box.
Anni [7]

Answer:

3x^{2}y^{2}\sqrt[4]{7xy^{3}}.

Step-by-step explanation:

Since we have to find the simplified form of the expression as below

\sqrt[4]{567x^{9}y^{11}}

we will solve the expression as below

=[567x^{9}y^{11}]^{\frac{1}{4}}

=(81\times 7)^{\frac{1}{4}}\times x^{\frac{9}{4}}\times y^{\frac{11}{4}}

=81^{\frac{1}{4}}.7^{\frac{1}{4}}.x^{\frac{8}{4}+\frac{1}{4}}.y^{\frac{8}{4}+\frac{3}{4}}

=(3^{4})^{\frac{1}{4}}.7^{\frac{1}{4}}.x^{2+\frac{1}{4}}.y^{2+\frac{3}{4}}

=3^{1}.7^{\frac{1}{4}}.x^{2}.x^{\frac{1}{4}}.y^{2}.y^{\frac{3}{4}}

=3.x^{2}.y^{2}.(7^{\frac{1}{4}}.x^{\frac{1}{4}}.y^{\frac{3}{4}})

=3x^{2}y^{2}.(7xy^{3})^{\frac{1}{4}}

=3x^{2}y^{2}\sqrt[4]{7xy^{3}}.

Round 713,949 to the nearest hundred
TEA [102]

Answer:

<em>713,900</em>

Step-by-step explanation:

713,<u><em>9</em></u>49

The bold, italic, underlined digit is the hundreds digit.

To round to the nearest hundred, change all digits to the right of the hundreds digit to 0. Now you have

713,900

There is one more step. Look at the first digit that used to be to the right of the hundreds digit. If it is from 1 to 4, the hundreds digit remains the same. If it is from 5 to 9, the hundreds digit goes up by 1. In this case, the first digit to the right of the hundreds digit was 4, so the hundreds digit does not go up by 1.

Answer: 713,900
