43 tens = 43 x 10 = 430
3 tens = 3 x 10 = 30
Multiply the two numbers together
430 x 30 = 12900
12900 is your answer
hope this helps
Answer:
16.2 units
Step-by-step explanation:
Greater angle: 180 - 72 = 108
D² = 10² + 10² - 2(10)(10)cos(108)
D² = 261.8033989
D = 16.18033989

Determine g(x), if f(x) is reflected across the y axis
<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>
<em />
In other words,

Calculating f(-x)


Substitute g(x) for f(-x)

<em>Hence;</em>

24 * 3/4 = 18
The radius of smaller cone is 3/4 the radius of original cone, so since these cones are similar, height must also be 3/4 times smaller.
So since radius is squared and we also multiple the height (V = 1/3 π r² h),
the volume of smaller cone would be 3³ / 4³ = 27 / 64 times smaller
So we have 1920 * (27 / 64) = 810.
Final answer: B
