Simplify the expression
6² + 9²
6² = 6 x 6 = 36
9² = 9 x 9 = 81
36 + 81 = 117
117 is a rational number ∴ <span>6</span>²<span> plus 9</span>² is rational
hope this helps
Answer:
A. 78,5 in
Step-by-step explanation:
Formula for circumference of the circle is π × diameter.
<h2>:- Question</h2>
Find the circumeference of the circle!
<h2>:- Solution</h2>
Circumeference = π × diameter
= 3,14 × 25 in
= 78,5 in
The circumeference of the circle is 78,5 in
_______________________
1. Area of a circle is pi x R^2
Area = 3.14 x 18^2
Area = 3.14 x 324= 1017.36 sq. In.
The blade covers 122 out of 360 degrees.
1017.36 x 122/360 = 345 square inches.
2.
Like above.
Area =3.14 x 75^2 = 17,662.5 square feet
17662.5 x 80/360 = 3,925 square feet.
Answer:
g(f(2)) = 9
Step-by-step explanation:
Evaluate f(2) and substitute the value obtained into g(x)
f(2) = 2 + 1 = 3 , then
g(3) = 3² = 9
