R = √5 ≈ 2.236 ≈ 2.24
2.24 x 2.24 x 3.14 = 15.755264 ≈ 15.8
Answer:
<h3>
This means that about 21 level truck loads are necessary to remove all dirts.</h3>
Step-by-step explanation:
To get the number of level truck loads needed to remove all the dirts in the house, first we need to calculate volume of the truck and the house.
Volume of truck = Length * Breadth * Height
If the truck is 5.0 for the length 2.0 for the height 3.0 for the side base;
Volume of the truck = 5*2*3
Volume of truck = 30
For the house;
Volume of house = Length * Breadth * Height
If the house is 4.0 for the height 14.5 for the length and 11.0 for the side base, then
Volume of the house = 4*14.5*11 = 638
Number of level truck loads needed to remove all the dirts = Volume of house/Volume of the truck = 638/30 ≈ 21.3
This means that about 21 level truck loads are necessary to remove all dirts.
The complete question in the attached figure
we know that
When we know <span>two sides and the included angle the formula for calculate the area is
</span>Area=(1/2)*a*b*sin C
in this problem
let
a=20
b=12
C=68°
Area=(1/2)*20*12*sin 68°------> Area=111.26 units²-----> Area=111.3 units²
the answer is111.3 units²
4m 8cm is equal to 408cm divide that by 10 equals 40.8cm
