ratelena [41]3 years ago
4 0

Answer:

length :16cm

wide :20cm

We have

Area of inner frame :16*20=320cm²

For

Total area =464cm²

(20+2x)(16+2x)=464cm²

320+32x+40x+4x²=464cm²

4x²+72x+320-464=0

4x²+72x-144=0

4(x²+18x-36)=0

x²+2.9.x+9²=9²+36

(x+9)²=117

x+9=√117

x=10.81-9

x=1.82[approximately]

So

<u>width of frame;20cm+1.82+1.82=23.64cm</u>

<u>length: 16+1.82+1.82=19.64cm</u>

Here length is smaller than breadth.

A section of concrete pipe 30m long has an inside diameter of 1.2m and an outside diameter of 1.8m. what is the volume of concre
Fudgin [204]

length of pipe= 30m

Inside dia. = 1.2m

Outside dia. = 1.8m


Volume of concrete= (outside dia. - inside dia.)h

V= (pi)
v= [(3.14*0.9*0.9)-(3.14*0.6*0.6)]30

v= (3.3534-1.1304)30
v=(2.233)30 = 66.690m cube

since it's volume the answer 66.690 is in cubic meters.
