The formula for the area of a triangle of base b and altitude h is A = (1/2)(b)(h).
Here, b = 18 cm and h = 9 cm. Thus, the desired area is:
(18 cm)(9 cm)
A = ----------------------- = 81 cm^2
2
This problem gives you more info than is needed to solve it. The area of the given triangle is 81 cm^2.
<span>A.
The surface area of A is greater than the surface area of B.</span>
The answer is: [C]: " 3.200 * 10⁷ h " .

Explanation:
________________________________
19.2 * 10⁸ min * (1 hr / 60 min) ;
= (19.2 * 10⁸)
_______________ ;
60
_____________________________
Divide EACH SIDE of the fraction by "10" ; to get:
___________
(19.2 * 10⁷)
_______________ ;
6
<span>______________________________
</span>⇒ (19.2) ÷ (6) = 3.2 ; so rewrite as:

Answer: Area= 459.73cm^2
Step-by-step explanation: Circumference of a circle is 2πr
76=2×3.14×r
r= 76÷(6×3.14)
r=12.10
Area of a circle= πr^2
Area= 3.14×(12.10)^2
Area= 456.73cm^2
