Lets get started :)
The first question requires the area of the circle with a radius of 5 meters
Area formula of a circle is;
A = [tex] \pi [/tex]r²
= [tex] \pi [/tex](5)²
= 25[tex] \pi [/tex] square meters
So your answer will be Option B
The second question asks us to find the area of the remaining rectangle
We have a rectangle with given length to be 10 in and width of 6 in
The Area formula of a rectangle is:
A = length x width
= 10 x 6
= 60 in²
We have a triangle within the rectangle with a base of 1.5 in { 10 - 8.5 } and a height of 1.5 in { 6 - 4.5 }
The Area formula of a triangle is:
A = [tex] \frac{1}{2} [/tex] x base x height
=[tex] \frac{1}{2} [/tex] x 1.5 x 1.5
= 1.125 in²
For finding the remaining area of the rectangle after removing the triangle, we need to subtract the area of the triangle from the area of the rectangle
Remaining area = Area of rectangle - Area of triangle
= 60 - 1.125
= 58.875 in²
So your answer will be Option C
