Circumference = 2 X PI X r
orange circle r = 5cm
circumference = 2 x 3.14 x 5 = 31.4 cm
blue circle r = 5+5 = 10
circumference = 2 x 3.14 x 10 = 62.8 cm
The coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
<h3>How to determine the image of point B?</h3>
The complete question is added as an attachment
From the attached image, we have the following coordinate
B = (-2, 4)
When the triangle is rotated by 270 degrees, the rule of rotation is:
(x, y) ⇒ (y, -x)
For point B, we have:
B' = (4, 2)
Hence, the coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)

Answer:
102.56
Step-by-step explanation:
136.75 - 25% = 102.56
25% of 136.75 = 34.19
Answer:
9.43 miles and for the diagram just draw a labelled right triangle with the base running towards the left. Hope this helps!
Step-by-step explanation:
I believe you would use the pythagorean theorem which is a^2+b^2=c^2
So if
8^2+5^2=c^2
64+25=89
\sqrt{89} = 9.43
Answer:
90%
Step-by-step explanation:
cost price of both tv = 2500
sale price of undamaged = 3000
sale price of damaged = 2200
sale price of both tv = 5200
profit = sale price - cost price
profit = 5200 - 2500
profit = 2700
profit percentage = profit × 100 ÷ cost price
profit percentage = 2700 × 100 ÷ 2500
profit percentage = 90%
