A 25/9 <br> B 125/9<br> C 32 <br> D 64
andrezito [222]

Answer:

Length = 5 feet

Breadth = (5/3) feet

Height(depth) = 2 feet

Volume of the entire tank = Length x Breadth x Height  

                                         = 5 \times \frac{5}{3}  \times2 = \frac{50}{3}   ----------(1)

Water is filled upto a height of (1/3) feet

Volume of water in the tank = Length x Breadth x Height  

                                           = 5 \times \frac{5}{3} \times \frac{1}{3}  = \frac{25}{9}     -------------(2)

Volume of space needed to be filled = (1) - (2)

                                                         = \frac{50}{3} -\frac{25}{9}  = \frac{150-25}{9}  = \frac{125}{9}  cubic feet

                                           OR

Height of tank needed to be filled = 2 - (1/3) = (5/3) feet

Volume of space =  Length x Breadth x Height of empty tank

                           =  5 \times \frac{5}{3} \times  \frac{5}{3}  = \frac{125}{9}  cubic \ feet

SOMEONE HELP!!!
Tasya [4]

Step-by-step explanation:

a) here,

diametre = 19 cm

Area = ?

Now,

Area = pie d

= 22/7 *19

59.71 cm2

Therefore, area = 59.71 sq.cm.

b)

here,

Area = 1000 sq.cm

diametre = ?

Now ,

Area = pie d

1000 = 22/7 *d

7000 = 22 * d ( cross multiply between 7&1000)

7000/22 = d

318.18 = d

Therefore, diametre = 318.18 cm .
