In order to get how much is being covered, we need to know the formula of the area of a circle.
Area = pi * r^2
Area = pi * (16/2)^2
Area = pi * 8^2
Area = pi * 64
Area = 200.96 in^2
So the correct answer is letter B. 200.96 in^2
Answer:
Step-by-step explanation:
1) we have to find the area of the cut out portion
Since both circles in one side makes up the side 28cm
The diameter of each circle is 14cm
radius = diameter / 2
r = 7cm
Area of a circle = πr²
A = 22/7 × 7²
= 22/7 × 7 × 7
= 22 × 7 = 154cm²
So the four circles will make
= 154 + 154 + 154 + 154
= 616 cm²
The Area of the square will be
= L × L
= 28 × 28
= 784 cm²
Therefore the area of the remaining portion will be
Area of the square - total area of the circles
= 784 cm² - 616 cm²
= 168 cm²
The area of the remaining part is 168 cm²
Answer:
Let's assume the number is 100 now it is increased by 50% that means
100+ (50/100)*100
100+50=150
Now it is decreased by 25% that means
150- (25/100)*150
150–37.5=112.5
Total percentage increase ={(112.5–100)/100}*100
=12.5%
Step-by-step explanation:
10% of $20 is $2 (take off the end 0)
$20+10%=?
$20+$2[this is 10%]=$22
The selling price is $22
The answer is (5p+6q)(5p-6q)
Steps:
Apply difference of the squares rule: x^2-y^2=(x+y)(x-y)
25p^2-36q^2=(5p+6q)(5p-6q)
Hope this helps you! (:
