OPTION C
Equation of straight line is y=mx+c ,here m is slope in given question m is 1/4.
Hope it helps you.
C. You would first have to divide A by Pi, then take the square root of r, in order to get r by itself.
Answer:
706.5 ft^2
Step-by-step explanation:
area = radius^2 (Pi)
15^2(3.14) = 706.5
Answer:
The area of the tablecloth showing is approximately 45.55 square feet
Step-by-step explanation:
The diameter of the dinner table, D = 8 feet
The diameter of each plate, d = 1 feet
The number of people at the dinner table = 6 people
The number of plates = 6 plates
The area of the table cloth, A₁ = π·D²/4
∴ A₁ = π × 8²/4
The area covered by the 6 plates, A₂ = 6·π·d²/4
A₂ = 6 × π × 1²/4
Let 'A' represent the area of the tablecloth showing when the table is set for six people, we have;
A = A₁ - A₂
∴ A = π × 8²/4 - 6 × π × 1²/4 ≈ 45.55 ft.²
The area of the tablecloth showing when the table is set for six people, A ≈ 45.55 ft.²
