Answer:
You need to find the surface of each area and sum them up.
Step-by-step explanation:
You will need the surface area for each side.
So 2 up-bottom, 2 left-right and two front-back
2*(4*3) + 2*(2*4) + 2(3*2)
2*12 + 2*8 + 2*6
24 + 16 + 12
Total area = 52
X^2+8x-3>-19 | +19
x^2+8x+16>0
x^2+4x+4x+16>0
x(x+4)+4(x+4)>0
(x+4)(x+4)^2>0
this is true cause (X+4)^2 >0 cause X+4>0
Answer:
Area = π r^2.
Step-by-step explanation:
Given the radius r of a circle, the area = π r^2.
So for example the area of a circle of radius 2 = π 2^2
= 4π.
Step-by-step explanation:
1. draw the parallelogram with side 20cm and 25cm respectively and also the diagonal as well.
2.Clearly it forms a triangle in the parallelogram with three known lengths of side.
3.Using the cosine rule : c^2=b^2+c^2 -2bc cos c to find the obtuse angle.
