Help please with this math ;-; I beg of you
RSB [31]

Answer:

49 - 9π

Step-by-step explanation:

Area of white portion = area of triangle - area of circle

To find the area of the triangle:

The area of a triangle can be calculated using this formula

A=\frac{bh}{2} where b = base length and h = height

The height given is 7m and the base length given is 14m

That being said we plug in the given values into the formula

\frac{14*7}{2} \\14*7=98\\\frac{98}{2} =49

Hence, the area of the triangle is 49 sq meters.

To find the area of circle

( note that the area is in terms of pi; shown by the answer choices. )

Formula for area of a circle = A=\pi r^2

We are given the diameter  ( 6m )

However, we need the radius

To convert diameter to radius we divide by 2

6/2 = 3 so the radius = 3m

Now we plug in 3 into the formula

A=\pi 3^2\\3^2=9\\A=9\pi

Remember we do not apply pi because the answer should be in terms of pi.

Now we subtract the two

Area of white portion = 49 - 9π

Hence, the answer is A

(X-1) squared + y squared = 36. What is the center and radius of the circle
Leni [432]

Answer:

  • center (1, 0)
  • radius 6

Step-by-step explanation:

<u>Given</u>

  (x -1)^2 +y^2 = 36

<u>Find</u>

  the circle's center and radius

<u>Solution</u>

Compare the given equation to the standard form equation for a circle.

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . centered at (h, k) with radius r

This tells you ...

  • h = 1
  • k = 0
  • r = √36 = 6

Your circle is centered at (1, 0) and has a radius of 6.

The 15th term of arthimetic sequence is 43 and the common difference is 4 find the first term
Digiron [165]

Answer:

Step-by-step explanation:

hello :

the nth term of an arithmetic sequence is :

An =An+(n-p)d   ....a common difference is : d  

let : n=15    and   p=1    d= 4     A15 =43

A15 = A1 + (15-1)(4)

43= A1 +56

A1= 43-56 = - 13
