Answer:
C
Step-by-step explanation:
This has to be C because you need to divide pi from r squared bc they r multiplied. Then you get a/pi = r squared. You need to find the square root of a/pi. So r equals square root a/pi.
Answer:
360cm²
Step-by-step explanation:
area of the parallelogram = base x height
base = 40 -10= 30cm
height = height of the triangle
A = 30*12= 360
Answer:
<h2>
Check A, B and D </h2>
Step-by-step explanation:
A. m∠4 = 180° - m∠3
m∠1 = 180° - (m∠3 + m∠2)
m∠3 < m∠3 + m∠2 ⇒ m∠4 >m∠1
B. m∠4 = 180° - m∠3
m∠2 = 180° - (m∠3 + m∠1)
m∠3 < m∠3 + m∠1 ⇒ m∠4 >m∠2
C. Not necessarily {could be but not always}
D. m∠4 = 180° - m∠3
m∠1 + m∠2 + m∠3 = 180° ⇒ m∠1 + m∠2 = 180° - m∠3 = m∠4
E. m∠3 = m∠1 + m∠2 only if m∠3 = 90°
F. Not necessarily. {Could be but also could not be. In the picture is, but we don't know if the diagram is accurate or just approximate.}
Answer:
A = 94.2 cm²
Step-by-step explanation:
Given that,
Length, l = 5 cm
Width, b = 2 cm
Height, h = 5.3 cm
We need to find the surface area of the solid cuboid.
The formula for the surface area of the sold cubiod is given by :
A = 2(lb+bh+hl)
Substitute the values in the above formu;a
A = 2(5(2)+2(5.3)+(5.3)(5))
= 2(10+10.6+26.5)
= 2(47.1)
= 94.2 cm²
Hence, the required surface area is 94.2 cm².
It would be A since in the equation (x+4)^2-2 the plus 4 means horizontal shift to the left and -2 means vertical shift down 2
