Find the length of the arc to 2 decimals places

Mathematics
1 answer:
HACTEHA [7]3 years ago
7 0

Answer:

Step-by-step explanation:

The formula for arc length is

AL=\frac{\theta}{360}*2\pi r where theta is the measure of the central angle and r is the radius. We have both of those pieces of info; filling in:

AL=\frac{30}{360}*2(3.14) (4) and simplifying a bit:

AL=\frac{1}{12}(8)(3.14) and a bit more:

AL=\frac{25.12}{12} and finally, to

AL = 2.09 m

The surface area of a cube is 96 square inches. What is the length of an edge of the cube, in inches?
Bezzdna [24]

Answer:

16 inches

Step-by-step explanation:

A cube has 6 sides and to find the surface area you would multiply one side by 6, or add the six sides together. So instead, to find the length of one side, you divide the surface area, 96, by 6 to get 16.

Hope this helps you :)

9a-18b+21c apply distributive property to factor out gcf of all three terms
horsena [70]
The GCF of the three terms (9a, -18b and 21c) is 3

Rewrite each of the terms so 3 is a factor
9a = 3*3a
-18b = -3*6b
21c = 3*7c

So we can say...
9a - 18b + 21c = 3*3a - 3*6b + 3*7c
9a - 18b + 21c = 3(3a - 6b + 7c)

Answer: 3(3a - 6b + 7c)

If you distribute outer 3 to each of the inner terms and multiply, you'll get the original expression again.

The diagram below shows a rectangle with a shaded region. What is the area, in square meters, of the shaded region in the diagra
Mila [183]

Answer:

Step-by-step explanation:

Area of shaded region= area of rectangle- area of triangle

Area of rectangle= l×b

                            =9×3

                            = 27m²

Area of triangle= \frac{1}{2} b×h

                        =\frac{1}{2} ×3×3

                        =\frac{9}{2} ⇒4.5

Area of shaded region= area of rectangle- area of triangle

                                     =27-4.5

                                     =22.5m²
