I think the answer is (a)
Yes, the triangle is right angled.
Step-by-step explanation:
Given lengths are;
11 yards, 60 yards and 61 yards
From pythagoras theorem;
The sum of square of shorter lengths is equal to square of larger side.
Here;
a = 11 , b = 60 , c = 61

As it satisfies the condition of Pythagoras theorem, the triangle is right angled.
Yes, the triangle is right angled.

The answer would be 3,799.4 I don’t know how to get it to the nearest hundredth because I used my phone calculator but to find the answer you would take radiusxradiusxheightxpi so 11x11x10x3.14
Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
