Question 60/62 (3.p.)
Vsevolod [243]

Answer:

Capacity of tank = 44,000 l

Step-by-step explanation:

Given:

Height of tank = 3.5 m

Radius = 2 m

Capacity of tank

Computation:

Volume of cylinder = πr²h

Volume of cylinder = (22/7)(2)²(3.5)

Volume of cylinder = 44 m³

1m³ = 1000 l

Two Dimensional Nets and Surface Area - Quiz - Level
Virty [35]

Answer:

18\ ft^2

Step-by-step explanation:

The complete question in the attached figure

we know that

The surface area of a cube is equal to the area of its 6 squares faces

so

The area of one square face is equal to

A=b^2

where

b is the length side of the square

we have

b=1\ ft

substitute

A=(1)^2=1\ ft^2 ---> area of one square face

Find the surface area of three cubes

Multiply the area of one square face by 6 (one cube has 6 faces) and then multiply the result by 3 (3 cubes)

so

SA=3[6(1)]=18\ ft^2
