Area of one face=80/4=20
base length=10
area =1/2*10*h=20 where h is slant height.
h=20/5=4
so slant height h=4 cm
Ax + by =12; 2x + 8y = 60. ax + by = 12; 2x + 8y = 60
Answer:
Step-by-step explanation:
3.
The formula of a volume of a sphere:
R - radius
We have R = 3.15 m. Substitute:
4.
The formula of a volume of a cone:
r - radius
H - height
We have 2r = 11.6 → r = 5.8 and H = x. Substitute:
6.
The formula of a volume of a cube:
s - edge
We have s = 1.02 in. Substitute:
The angles will help you tell the difference. In a rectangle, all angles are 90 degrees. In a rhombus, the 2 opposite facing angles are the same and all side lengths are the same.
