Need in geometry right answers only give me now 25 points

The area of the circle = π r² = π (d/2)²
Where r is the radius of the circle 
And d is the diameter of the circle 
d = 2r   OR   r = d/2
given d = 10 in   ∴  r = d/2 = 10/2 = 5 in
∴ The area of the circle = π r² = π * 5² = 25π ≈ 78.54 in²

The correct answer is the fourth option 78.54


very important note:
There is a mistake in the dimension of the answers.
The dimension of the given diameter is inch , while the dimensions of the answers is square cm.

If it is required to find the area in square cm
∵ 1 inch = 2.54 cm
∴ r = d/2 = 10/2 = 5 in = 5 * 2.54 cm = 12.7 cm

∴ Area = π r² = π * (12.7)² = 161.29π ≈ 506.7 square cm

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

this > inequality sign means:

this < inequality sign means:

this > inequality sign means:

this < inequality sign means:

about the problem:

since the line is solid, that means it's either < or >
