Answer:
The surface area of door is 33 680 cm².
Step-by-step explanation:
Given that the surface area of a cuboid which is the 3D of rectangle is :
Answer:
you would do the positive number and then the fraction. for example if i had 2 1/2 i would move over on the x line if it was the first number or y line if it was the second number. say it was x, i would move toward positive numbers 2 times and the half way to 3 since 2 1/2 is a mixed fraction

Our aim is to calculate the Radius so that to use the formula related to the area of a segment of a circle, that is: Aire of segment = Ф.R²/2
Let o be the center of the circle, AB the chord of 8 in subtending the arc f120°
Let OH be the altitude of triangle AOB. We know that a chord perpendicular to a radius bisects the chord in the middle. Hence AH = HB = 4 in
The triangle HOB is a semi equilateral triangle, so OH (facing 30°)=1/2 R. Now Pythagoras: OB² = OH² + 4²==> R² = (R/2)² + 16
R² = R²/4 +16. Solve for R ==> R =8/√3
OB² = OH² +
Answer:
V = 196 mm³
Step-by-step explanation:
( 7/21 )³ = V / 5292
343 / 9261 = V / 5292
9261 V = 343 * 5292
V = 196 mm³
