Yes it is. Hope it helps.:)
36-12=24
The answer is:
12;24 or 1;2 (simplified)
circumference =2πr=2× 7 22 ×28=22×8 =176 cm
Area =πr 2 = 7 22 ×28×28=88×28 =2464 cm 2
<u><em>circumference=176 cm </em></u>
<u><em>Area= 2464 cm 2</em></u>
The area of a triangle in terms of height and base is A = 1/2*base*height
Suppose base = 6 cm and height = 12 cm. Then, A = 1/2*6*12 = 36 cm2.
If the base and height are scales by a factor of 5, b= 30 cm and h = 60 cm. Then, A = 1/2*30*60 = 900 cm2.
Thus the area of the resulting triangle is scaled by a factor of 25, which is 900 cm2.
