A craftsman makes a circular table with a radius of 55
Rudik [331]

Answer:

Hey mate here is your answer...

Step-by-step explanation:

smaller circular table to be made

with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm

therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm

circumference of circle = 2πr

= 2*3.14*27.5

= 172.7 cm = 27.5cm

hope it helps you ❣️

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $19. A second mixture included 16 lb
zubka84 [21]

Hey there!!

Take the cinnamon tea as ' x ' and spice tea as ' y '

10 x + 2y = 19  -------------- ( 1 )

16x + 10y = 44 --------------- ( 2 )

Multiply the first equation by 5

50x + 10y = 95

16x + 10y = 44

Subtract the second equation from the first

34x = 51

x = 51 / 34

x = $1.5

Substitute this in any other equation

15 + 2y = 19

2y = 4

y = 2

Cinnamon = $1.5

Spice tea = $2

Hope helps!

horsena [70]
The volume of the resulting solid will be the volume of one rectangular prism times n.
The the volume of a rectangular prism is V=lwh. But since l=w (cross-section is a square), we now have V=l²h.

The volume of the resulting solid will be V = nl²h or V = nw²h.
