Find the later area of the figure

Mathematics
1 answer:
o-na [289]3 years ago
3 0

Answer:

\large\boxed{60\pi\ sq.in.}

Step-by-step explanation:

The formula of a lateral area of a cone:

L.A.=\pi rl

r - radius

l - lateral height

We have the radius r = 6in and the height H = 8in.

Use the Pythagorean theorem to calculate the lateral height:

l^2=6^2+8^2\\\\l^2=36+64\\\\l^2=100\to l=\sqrt{100}\\\\l=10\ in

Substitute:

L.A.=\pi(6)(10)=80\pi\ in^2

2.49 is rounded to 2.50

Therefore:

86 - 25 - 2.50 = 59.50

Given: f(1) = 3x– 7, 9(x) = 2x^2 – 3x +1, h(x) = 4x + 1, k(x) = –x^2+3<br> Find: (h o g) (x)
grin007 [14]

Answer:

(h o g) (x) = h(g(x))

Step-by-step explanation:

(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1

= 4*2x^2 - 4*3x + 4*1 + 1

= 8x^2 - 12x + 4 + 1

= 8x^2 - 12x + 5

Based on the investment ratio and the amount invested, the amount that Zach invested is<u> $102,857.14. </u>

First thing to do is to add up the numbers in the ratio:

= 1 + 2 + 0.5

= 3.5

The amount that Zach invested is:

<em>= Zach's ration/ Sum of ratio x Amount invested</em>

= 1 / 3.5 x 360,000

= $102,857.14

In conclusion, Zach invested $102,857.14.
