Answer:
Step-by-step explanation:
The shaded region is the difference of areas of semicircle AB and triangle ABC.
ABC is right triangle as AB is diameter, so C is right angle.
<u>Area of semicircle:</u>
- A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²
<u>Area of triangle:</u>
- A = 1/2BC*AC = 1/2*4*
= 2
= 13.86 cm²
<u>Shaded are is:</u>
- 25.12 - 13.86 = 11.26 cm²
I think the first one is B and the second one is A
Answer:
height = 5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = A h ( A is the area of the base and h the height )
Here V = 180 cm³ , thus
6²h = 180 ( A of square = 6² = 36 )
36h = 180 ( divide both sides by 36 )
h = 5 cm
12 units, hmm.. I think your answer is correct.
True!
