Answer:
A) 50
Attached is the image of the figure.
Step-by-step explanation:
Area of a circle can be expressed as;
Area A = πr^2 ......1
Where;
r = radius
From the attached image, the shape is a Circle and the diameter of the circle is 8 units.
Diameter d = 8
Radius r = diameter/2 = 8/2 = 4 units
Substituting the radius into equation 1;
Area A = π × 4^2 = 16π
Area A = 50.265
Area A = 50 square units (approximately)
<u>Solid figure</u><u> is also known as flat </u><u>two-dimensional</u><u> shape which only has length and width.</u>
- Geometrically figure , 2-dimensional shapes or objects are flat planar figures with two dimensions—length and width.
- Shapes that are two-dimensional, or 2-D, have only two faces and no thickness.
- Two-dimensional objects include a triangle, circle, rectangle, and square.
What geometric figure is also known as a flat?
- A closed two-dimensional, or flat, figure is called a plane shape.
- Different plane shapes have different attributes, such as the number of sides or corners (or vertices).
- A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet.
What geometric figure is also known as?
Geometric figures are often classified as space figure, plane figure, lines, line segments, rays, and points depending on the dimensions of the figure.

Answer:
10/9
Step-by-step explanation:
This equation is in slope-intercept form, this is referring to the y-intercept. Slope-intercept is y=mx+b, where m is the slope and b is the y-intercept. Therefore, 10/9 is the intercept while -8 is the slope.
You need 864.52 sq. in. of blue tile.
We need to find the area of the large circle (including blue and yellow) and the area of the yellow circle.
We have the circumference of the blue circle, 113.097.
C = πd
113.097 = 3.14d
Divide both sides by 3.14:
113.097/3.14 = 3.14d/3.14
36.018 = d
The diameter is twice as much as the radius, so r = 36.018/2 = 18.009.
The area of a circle is given by the formula
A = πr²
A = 3.14(18.009)² = 1018.38 sq. in.
The area of the small yellow circle is given by
A = 3.14(7²) = 3.14(49) = 153.86
Subtracting these two, we have
1018.38 - 153.86 = 864.52 sq. in.
Answer:
3398
Step-by-step explanation:
(-34×-96=3264) + (-38×-4=152)
3246+152=3398
