the answer is 11/7 feet because the perimeter of a circle is πr² and a semi circle is half of a circle then the formula would be 1/2 πr² 1/2×22/7×1 (it is 1 because we have divided the diameter to get radius so we derived at 11/7.

Answer:
The normal price of mixer is $150.
Step-by-step explanation:
Given that:
Normal prices are reduced by 15% in sale.
The normal price of mixer is reduced by $22.50
It means that it is the amount of discount.
Let,
x be the normal price of the mixer.
15% of x = 22.50
Dividing both sides by 0.15
Hence,
The normal price of mixer is $150.
