Based on the definition of <em>composite</em> figure, the area of the <em>composite</em> figure ABC formed by a semicircle and <em>right</em> triangle is approximately 32.137 square centimeters.

<h3>How to find the area of the composite figure</h3>

The area of the <em>composite</em> figure is the sum of two areas, the area of a semicircle and the area of a <em>right</em> triangle. The formula for the area of the composite figure is described below:

A = (1/2) · AB · BC + (π/8) · BC²     (1)

If we know that AB = 6 cm and BC = 6 cm, then the area of the composite figure is:

A = (1/2) · (6 cm)² + (π/8) · (6 cm)²

A ≈ 32.137 cm²

Based on the definition of <em>composite</em> figure, the area of the <em>composite</em> figure ABC formed by a semicircle and <em>right</em> triangle is approximately 32.137 square centimeters.

What is the volume of the cone with radius 4 ft and height 10 ft? Round to the nearest cubic foot.
umka2103 [35]

Answer:

D) 168 ft3

Step-by-step explanation:

The formula to find the volume of a cone is V=πr^{2}\frac{h}{3}.

We need to plug in the radius, 4, and the height, 10, into this equation.

V=π(4)^{2}\frac{10}{3}

V=π16\frac{10}{3}

V=π53.33

V=167.55

If we round up to the nearest whole number, we get 168 ft^{3}. Therefore, the correct answer is D) 168 ft3.

I hope I helped!

10. Solve the equation: h/9= 7.<br> O A. h = 63<br> B.h=-63<br> O C. h = ?19<br> D. h=1211
Elan Coil [88]

h/9=7

Multiply by 9 for both sides.

h/9( 9)=7(9)

Cross out 9 and 9, divide by 9 then becomes h

h=63

Answer:  A. h = 63

Jim 3 bought 3 hamburgers and 4 orders of french fries for $10.77 before taxes.
Inessa [10]

Answer:

The cost of one hamburger is $2.19.

Step-by-step explanation:

Let h = cost of a hamburger

f = cost of a french fries

3h + 4f = 10.77-------->3h + 4f = 10.77

4h + 2f = 10.86------->8h + 4f = 21.72

---------------------

5h = 10.95

h = 2.19, f = 1.05

Today, George is three times as old as his sister Lucy. In two years, Lucy will be half as old as George, How old will George be
saw5 [17]

Answer:

In two years, George will be 8 years old.

Step-by-step explanation:

g = 3s

(g + 2) / 2 = a + 2

g + 2 = 2 (s + 2)

g + 2 = 2s + 4

g = 2s + 2

3s = 2s + 2

s = 2

g = 3s

g = 3 (2)

g = 6

6 + 2 = 8
