Answer: 21.994 cm²
Step-by-step explanation:
Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.
Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142
Now area of the bigger circle = 3.142 x 3²
= 3.142 x 9
= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2
= 6.284 cm².
Therefore are of the shaded region = 28.278 - 6.284
= 21.994 cm²
-15
Reason:
First, use the distributive property
3(2p - 5) - 6p = 6p - 15 - 6p = -15
Answer:
T
he volume of the drawers in the dresser is 1 ft
³
Step-by-step explanation:
To calculate the volume of a drawer, we first need to know that a drawer has a rectangular base prism shape
The formula to calculate the volume of a rectangular base prism is:
v = volume
w = wide
l = long
h = high
v = l * w * h
v = 2ft * 1ft * 1/2 ft
v = 1 ft
³
T
he volume of the drawers in the dresser is 1 ft
³
36/3=12
pythagorus theorem to find height: 12squared-6squared=108
height=10.4
area=1/2base*height
=1/2(12*10.4)
=62.4
Answer:
69 degree
Step-by-step explanation:
Using cosine formula again :))
So we have
BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA
BC^2 = 32^2 + 28^2 -2*28*32*cos56
BC = 28.3884 cm
So B:
AC^2 = AB^2 + BC^2 - 2*AB*BC*cosB
CosB=0.3559
B=69.14 degree
