5x - 10y = -40
-10y = -40 - 5x
y = -40 - 5x / -10
Answer:
678.24 cubic in.
Step-by-step explanation:
Ok, first find the area of the base.
3.14×3^2= 28.26
Then multiply that area by the height, which is 8×3=24
24×28.26=678.24
Let me know if you got it!
Answer
Formula

where r is the radius of a circle.
As shown in the image
Diameter of the circle = 16 .3 cm

= 8.15 cm
Put in the formula

As


= 51.2 cm (approx)
Therefore the circumference of a circle is 51.2cm (approx) .
Option (D) is correct .
Answer:
8 meters
Step-by-step explanation:
Given that:
Height of person = 2metres
Length of person's shadow = 6 meters
Height of flagpole =?
Length of flagpole shadow = 24 meters
Height of person = length of person's shadow
Height of flagpole = length of person's shadow
2 = 6
x = 24
Cross multiply
6x = 48
x = 48 / 6
x = 8 meters
Angle TVU = 1/2 (120 - 12) = 108/2 = 56°
Therefore, the correct answer is D.
