The area of circle Z is 64Pi ft2. Circle Z is shown. Radius D has length r. R = StartRoot StartFraction Area Over pi EndFraction EndRoot What is the value of r? r = 4 ft r = 8 ft r = 16 ft r = 32 ft
Answer:
r = 8 ft
Step-by-step explanation:
Area of a circle => πr²
We are told in the question that:
The area of circle Z is 64Pi ft²
= 64π ft²
What is the value of r
We equate
πr² = 64 π
r² = 64 π/π
r² = 64
We square root both sides.
√r² = √64
r =>8 ft
The radius of the given circle Z is 8ft which was solved using the area of the circle
Data;
Area = 64π ft^2radius = rArea of a CircleThe formula of area of a circle is given as
[tex]A = \pi r^2[/tex]
Let's substitute the values and solve
[tex]A = 64\pi\\A = \pi r^2 \\64 \pi = \pi r^2\\[/tex]
divide through by π
[tex]64\pi = \pi r^2\\\\64 = r^2\\[/tex]
Let's take the square root of both sides
[tex]r^2 = 64\\r = \sqrt{64} \\r = 8ft[/tex]
The radius of the circle Z is 8ft

*also pls look at both images :)*
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63

The area of the pier is approximately 1231.62 square meters.
What is a circle?A circle is a two-dimensional figure with a radius and circumference of 2pir.
The area of a circle is πr².
We have,
The pier is in the shape of a semicircle.
So,
The area of a semicircle is half of the area of a circle with the same diameter.
The area of a circle with a diameter of 56m is:
A = πr² = π(28)² = 2463.23 m²
So,
The area of the semicircle is:
A/2 = 2463.23/2= 1231.62 m²
Therefore,
The area of the pier is approximately 1231.62 square meters.

Answer:
f(x) = 3x³ +6x² -3x -6
Step-by-step explanation:
Each x-intercept (x=p) gives rise to a factor (x-p), so the factored form of the function is ...
f(x) = a(x -(-2))(x -(-1))(x -1)
The value of 'a' is chosen to make the y-intercept match that shown. The function just written has ...
f(0) = -6 = a(2)(1)(-1)
-6 = -2a
a = 3 . . . . . divide by -2
So, the function in factored form is ...
f(x) = 3(x +2)(x +1)(x -1)
Expanded, this is ...
f(x) = 3x³ +6x² -3x -6

Answer:
327 cm²
Step-by-step explanation:
The opposite faces of a cuboid are congruent , front and back, top and bottom, the two side faces, then
SA = 2(9.5 × 8) + 2(5 × 8) + 2(9.5 × 5)
= (2 ×76) + (2 × 40) + (2 × 47.5)
= 152 + 80 + 95
= 327 cm²
Answer:
Step-by-step explanation:
SA = 2B + LA B = area of base LA = lateral area
B = area of the rectangle with length of 9.5 and width of 5
= 9.5(5) = 47.5
LA = perimeter of base times the height
= [2(9.5) + 2(5)] (8)
= (19 + 10)(8)
= 29(8)
= 232
SA = SA = 2B + LA = 2(47.5) + 232
= 95 + 232
= 327 sq cm
