<u>Given</u>:
Given that the diameter of the circle is 10 kilometers.
We need to determine the area of the circle.
<u>Radius of the circle:</u>
The radius of the circle can be determined using the formula,

Substituting d = 10, we get;


Thus, the radius of the circle is 5 kilometers.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,

Substituting r = 5, we get;



Thus, the area of the circle is 78.5 square kilometers.
Answer:
23.38.
Step-by-step explanation:
Answer:
7x + 1 and 2a - 1
Step-by-step explanation:
(a)
2x + 1 + 5x ← collect like terms
= (2x + 5x) + 1
= 7x + 1
(b)
- 3a + 2 + 5a - 3 ← collect like terms
= (- 3a + 5a) + (2 - 3)
= 2a + (- 1)
= 2a - 1
