(a) The radius of a circle is 5.6 cm. Find the angle in degrees subtended by an arc of 22 cm at the centre of the circle.

DO NO A PLEASE​

225 degrees

Step-by-step explanation:

Given the following data;

To find the angle in degrees subtended by an arc;

Mathematically, the length of the arc of a circle is given by the formula;

S = rA

Where;

Substituting the values into the formula, we have;

22 = 5.6 * A

A = 3.9286 radians.

Next, we would convert the value of the angle in radians to degrees;

Conversion:

Cross-multiplying, we have;

X = 225.0015 ≈ 225 degrees

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
