I need 3 questions answered please.​
kakasveta [241]

Answer:

3) \:  \: 113 {ft}^{2}

4) \: false

5) \: 70 {ft}^{2}

Step-by-step explanation:

3) Area of a circle is

\pi \times  {r}^{2}

Where r = 6

Thus,

area =   \frac{22}{7}  \times  {6}^{2}

area =  \frac{22}{7}  \times 36

area = 3.143 \times 36

area = 113 {ft}^{2} \: (nearest \: whole \: number)

4) False

Area of a circle is measured by the formula below:

area = \pi \times  {r}^{2}

5) The formula for calculating the area of a rectangle is given thus:

area \: of \: a \: rectangle = l \times w

Where, l = 10ft; w = 7ft

area = 10ft \times 7ft = 70 {ft}^{2}

The volume of a sphere is 500 3 πcm3. What is the radius? Sphere V = 4 3 πr3 1. Substitute value into formula:  500 3 π = 4 3 πr
Kisachek [45]

Answer:

Radius of the sphere is 5m.

Step-by-step explanation:

We have given the volume of sphere \frac{500}{3}\cdot {\pi}m^3

we have to find the radius of the sphere

\text{volume of sphere is }=\frac{4}{3}\cdot {\pi}\cdot r^3

On substituting the given value of volume of sphere we get

\frac{500}{3}\cdot {\pi}=\frac{4}{3}\cdot {\pi}\cdot r^3

After simplification we get:

\Rightarrow 4\cdot r^3=500

\Rightarrow r^3=125

\Rightarrow r=5

Hence, the radius of sphere is 5m
