Answer:
81 degrees
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
20 = 2*pi*r
Divide each side by 2pi
20/2pi = 2*pi*r/2pi
10/pi =r
We know the arc length can be found by
s =r theta where theta is in radians
9/2 = 10/pi *theta
Multiply each side by pi/10 to isolate theta
9/2 * pi/10 = pi/10 *10/pi *theta
9*pi/20 = theta
We need to convert to degrees
9*pi/20 * 180/pi
81 degrees
Answer:
£2
Step-by-step explanation:
Let T represent T-shirt and H represent hat
5T + H = £27.00
2T + H = £12.00 Subtract two equation
5T + H - 2T - H = £27 - £12 ➡ 3T = £15 and T = £5 this is the cost for a t-shirt
If a t-shirt costs £5 and 2 t-shirt + a hat costs £12 then a hat costs £2
