The answer is no , because there is 0 twice !
Answer:
b
Step-by-step explanation:
Step-by-step explanation:
in an isoceles triangle both sides are equal.
take one of the half right angle triangle
by Pythagoras theorem
√45²=(3)²+(X/2)²
45=9+x²/4
45-36=x²/4
9*4=x²
X=6
option B
Answer:
43.13 yd squared
Step-by-step explanation:
This is a figure composed of a semicircle and a right triangle.
Triangle:
The area of a triangle is denoted by A = (1/2) * B * h, where b is the base and h is the height. Here, the base is actually also the radius of the semicircle, which is 4. The height is 9. Plug these in: A = (1/2) * 4 * 9 = 36/2 = 18 yd squared.
Semicircle:
The area of a semicircle is denoted by A = , where r is the radius. Here the radius is 4. So: A = ≈ 25.13 yd squared.
Adding these up: 18 + 25.13 = 43.13 yd squared
Hope this helps!
