Answer:

37.7 ft²

Step-by-step explanation:

2×3.14×r=30.77

<em>Divide both sides by 2</em>

3.14×r=15.385

<em>Divide both sides by 3.14</em>

r≈4.9

3.14×r²

3.14×4.9²=

24.01×3.14≈

75.4

75.4÷2=

37.7

Marina86 [1]

Step-by-step explanation:

Han is multiplying10x^4 by 0.5^3 and gets 5x^7 is not a polynomial because 0.5 is not an integer. What is the error in han’s thinking explain

On multiplying 10x⁴ by 0.5x³,

10x^4\times 0.5x^3=(10\times 0.5)x^{4+3}\\\\=5x^7

A polynomial is a combination of coefficients and variables. It is made up of one or more monomial. Han says that it is not a polynomial because 0.5 is not an integer. The statement is false. After multiplication we get 5x⁷. It has a variable x and constant 5. Hence, its is a polynomial.
