Answer:C=10

Step-by-step explanation:

Follow along with the picture below

The formula for this type of problem is a^2+b^2=c^2

We know that 6=a and 8=b so we fill in the formula and square them

we then add the two values we got which get us to 100=c^2

we want to get rid of that square with we square root bothe sides and get c and the square root of 100 is 10.

So C=10

baherus [9]

Answer:

B. 246 in^2

Step-by-step explanation:

A = pi r^2 theta /360   if theta is in degrees

A = * pi *(16)^2 * (110/360)

A =  *pi* 256 * 11/36

A = 2816/36 *pi

A = 245.74236 in ^2

Find the volume of the solid, please
dsp73

Answer:

V \approx=1436.8

Step-by-step explanation:

Variables and symbols:

  • r = radius
  • V = volume
  • A = surface area
  • C = circumference
  • π = pi = 3.1415926535898
  • √ = square root

Volume of a sphere in terms of radius:

V = \frac{4}{3}\pi r^3 , V \approx 4.1888r^3

To calculate the volume of a sphere:

Usually the hardest part is measuring or estimating the diameter of the sphere. Special tools exist for smaller parts like balls in ball-bearings, but it gets more complicated if the size is large. Knowing that the diameter is the largest internal measurement you can take should help.

Once you have the measurement, to find the volume use the formula above, in which π is the well-known mathematical constant equal to about 3.14159. To adjust for a half-sphere calculation, just divide the result by two.

Spheres and half-spheres are useful in engineering and architecture due to their property of being able to take equal amounts of pressure or force from each direction.

Solution:

V=\frac{4}{3} \pi r^{3} =\frac{4}{3} *\pi *7^{3}  \approx1436.75504

Round to nearest tenth: 1436.8

Help me 20 points ........................
Hitman42 [59]

Answer:

Step-by-step explanation:

First, you need to find the slope of the line. To do this you need to choose two points on the graph. The points you are given are (-2, 1) and (4, 6). Then use these to find the slope.

m=\frac{y2-y1}{x2-x1}

m=\frac{6-1}{4-(-2)}

m=\frac{5}{6}

You can then plug this and one of your chosen points into the slope-intercept formula

y-y=m(x-x)

y-1=\frac{5}{6} (x-(-2))

y-1=\frac{5}{6} x+\frac{5}{3}

y=\frac{5}{6}x+\frac{8}{3}
