A rectangle has four sides and the width and length are the same as the other width and length so 11 times 2 is 22 and 38-22 is 16 so the perimeter of the width added together is 16 so then divide them by 2 and the width of the rectangle is 8.
Answer:
Given diameter: r = d / 2 , Given area: r = √[A / (4 * π)] , Given volume: r = ³√[3 * V / (4 * π)] , Given surface to volume ratio: r = 3 / (A/V) .
Step-by-step explanation:
So, do that!
Answer:
This is the concept of geometry, we are required to calculate for the length of the sides of the rhombus; we know that a rhombus is a compressed square, this implies that all the sides are equal;
If one of the angles is 110° the other angle will be:
180-110=70°
thus using the cosine rule we can find the side lengths as follows;
c^2=a^2+b^2-2ac Cos C
thus
let side a=b=x in
shorter diagonal=c=4 in
C=70°
substituting this into the formula we get:
4^2=x^2+x^2-2*x*x Cos 70
4^2=2x^2-2x^2(0.3420)
16=2x^2-2x^2(0.3420)
dividing through by 2 we get;
8=x^2-0.3420x^2
8=0.6580x^2
x^2=12.15843
getting the square root of both sides get:
x=sqrt(12.15843
x=3.4869)
x=3.5 (1 d.p)
the length of the sides is 3.5
Answer:
2 groups
Step-by-step explanation:
13 times 3 is 39
39 is not 34
please mark me brainliest!!!
The answer is 3x - y = -7 (if you put both sets of coordinates in the place of x and y you get -7)
For example: 3•(-2) - 1 = -7
