Answer:
480 ft^3
Step-by-step explanation:
The formula is lwh/3 so plug in length, width, and height.
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
Answer:
A. 219.80 square centimeters
Step-by-step explanation:
The total surface area is given by ...
A = πr(r+s)
where r is the radius and s is the slant height. Filling in the given numbers, you get ...
A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²
Answer:
(x + 5)² + (y - 7)² = 13
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (- 5, 7) and r = , thus
(x - (- 5))² + (y - 7)² = ( )² , that is
(x + 5)² + (y - 7)² = 13 ← equation of circle
