the diameter is the number given, 7 and the radius is half of the diameter so radius=3.5
Answer:
A = 140°
B = 40°
C = 140°
Step-by-step explanation:
1. Since we know that opposite angles are equal, b = 40°
2. Since we also know that the angle of a line adds to 180°,
a = 180° - 40°
So, 140°
Then repeat step 1 to find C through A.
According to this chart, the area of a circle with a diameter of <span>2.2 m is
area=(pi)(r)^2=</span><span><span>(pi)(d/2)^2</span>
= (pi)(2.2/2)^2
= 1.21 (pi) m^2</span>
Step-by-step explanation:
Pythagoras (for right-angled triangles) :
c² = a² + b²
c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.
c = diagonal = 10 ft
therefore, the width of the rectangle is 10/2 = 5 ft
10² = 5² + b²
100 = 25 + b²
b² = 75
b = length = sqrt(75) = 8.660254038... ft
I believe that is it 100, since it is the only number listed that has factors and multiples.
Hope this helps!
