Answer:
200 %
Step-by-step explanation:
From the question above, the pencils increases from 75 to 225, so what we are looking for is the percentage increase
The formula for finding percentage increase is;
% increase = × 100%
First; we will find the difference between the two numbers i.e 75 and 225
Increase = New number - Original number
= 225 - 75
= 150
Then we divide the increase by the original number and then multiply by 100 %
That is;
% increase = × 100%
= 2 × 100%
= 200%
Therefore; the percentage increase is 200%

Answer:
Step-by-step explanation:
Given that the figure is made up of portion of a square and a semicircle, we have;
BC ≅ AB = 6 cm
The area of semicircle BC with radius BC/2 = 3 is 1/2×π×r² = 1/2×π×3² = 4.5·π cm²
Triangle ABC = 1/2 × Area of square from which ABC is cut
The area of triangle ABC = 1/2×Base ×Height = 1/2×AB×BC = 1/2×6×6 = 18 cm²
The area of the figure = The area of semicircle BC + The area of triangle ABC
The area of the figure = 4.5·π cm² + 18 cm² = .
