Answer:
The Answer is B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here diameter = 12, thus radius = 12 ÷ 2 = 6 and (h, k) = (2.5, - 3.5), thus
(x - 2.5)² + (y - (- 3.5))² = 6², that is
(x - 2.5)² + (y + 3.5)² = 36 ← equation of circle

Answer:Using the distributive property, the problem becomes:
5x2 * 3x5 + 5x2 * 2x - 5x2 * 8 and each set of factors may be rearranged as:
5 * 3 * x2 * x5 + 5 * 2 * x2 * x - 5x2 * 8 which becomes
15x7 + 10x3 - 40x2
Step-by-step explanation:
The length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to is 10.5ft.
<h3>What is the length of the arc of a circle?</h3>
The length of the arc of a circle is equal to the product of the circumference of the circle and the ratio of the angle made by the arc of the circle to 2π. It is given by the formula,
It is given that the radius of the circle is equal to 2 ft while the angle made by the arc at the centre of the circle is equal to . And we know the formula for the length of the arc, therefore, the length of the arc,
Hence, the length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to is 10.5ft.
