№1. Given: r=8 ft, π≈3.14
C=2×π×r=2×3.14×8=50.24=50.2 ft
A=π×r²=3.14×64=200.96=201 ft²
Answer: 50.2 ft; 201 ft²
№2. Given: D=11 cm, π≈3.14
d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm
C=2×π×r=πD=3.14×11=34.54=34.5 cm
A=π×r²=3.14×(5.5)²=94.985=95 cm²
Answer: 34.5 cm; 95 cm²
Given:
The graph of a radical function.
To find:
The domain of the given radical function.
Solution:
We know that, domain is the set of input values or we can say domain is the set of x-values for which the function is defined.
From the given graph it is clear that, for each value of x there is a y-value. It means the function is defined for all real values of x. So,
Domain = Set of all real numbers.
Therefore, the correct option is A.
The answer is:t=4 You welcome
Answer:
108.36 ft2
Step-by-step explanation:
Use the facts we already know and plug them into the equation.
a=12.6(8.6)
If we multiply both factors, we get 108.36.
So, the rectangle is 108.36 ft2
