Answer: 85.13

Step-by-step explanation:

We know:

Circumference = 2*3.14r

Area of a circle = 3.14r²

We need to find the radius given the circumference before solving for the area:

32.7 = 2*3.14r

32.7/6.28 = 6.28r/6.28

r = 5.20700637

Now that we know the radius, we can plug it in to find the area:

A = 3.14(5.20700637)²

A = 3.14(27.1129153)

A = 85.134554

The slope of a line passing through H (-2, 5) is -3/4. Which ordered pair represents a point on this line?
oksano4ka [1.4K]
Answer:
(6,-1)

Explanation:
The slope of the line can be calculated using the following formula:
slope = \frac{y2-y1}{x2-x1}

We are given that:
slope = -0.75
point (x1,y1) is (-2,5)

We will use each of the given points to calculate the corresponding slope, then compare the calculated slope with the given one.

For point (6,-1):
slope = \frac{-1-5}{6--2} = -0.75 ........> accepted choice

For point (2,8):
slope = \frac{8-5}{2--2} = 0.75 ........> rejected choice

For point (-5,1):
slope = \frac{1-5}{-5--2} = 4/3 ........> rejected choice

For point (1,1):
slope = \frac{1-5}{1--2} = -4/3 ........> rejected choice

Therefore, the first option is the only correct one.

Hope this helps :)

Find the total surface area of the triangular prism
GuDViN [60]

Answer:

1,008\:\mathrm{cm^2}

Step-by-step explanation:

The total surface area of this triangular prism consists of three rectangles and two triangles. Adding the areas of each of these shapes allows us to find the total surface area of this 3D figure:

Area of both triangles:

2\cdot \frac{1}{2}\cdot12\cdot 14=168\:\mathrm{cm^2}

Area of all three rectangles:

15\cdot 20 +13\cdot 20+14\cdot 20=840\:\mathrm{cm^2}

Therefore, the total surface area of this figure is:

840+160=\fbox{$1,008\:\mathrm{cm^2}$} \: \checkmark

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Helen [10]

Answer:

y=7x+1

Step-by-step explanation:

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

In this problem we have

m=7

point(1,8)

substitute and solve for b

8=7(1)+b

8=7+b

b=8-7=1

The equation of the line is equal to

y=7x+1
