Answer:

3√2

Step-by-step explanation:

1(3√2)2=2n

Multiply 2 and 1 to give 2

2(3√2)=2n

Multiply 2 and 3√2=6√2

6√2=2n

Divide both sides by 2

n=6√2/2=3√2

Arc are subtends a central angle measuring 3pi/5 radians . What fraction of the circumference is this arc?

Fofino [41]

Answer:

The arc is 3/10 of the circumference

Step-by-step explanation:

we know that

The complete circumference subtends a central angle of 2π radians

using proportion

Find out what fraction of the circumference represent an arc with a central angle of 3pi/5 radians

$\frac{1}{2\pi}=\frac{x}{(3\pi/5)}\\\\x=\frac{(3\pi/5)}{2\pi}\\\\x=\frac{3}{10}$

What is the height of a

vagabundo [1.1K]

Answer:

12 meters

Step-by-step explanation:

The area of a parallelogram can be found using:

a=bh

We know that the base is 7 meters, and the area is 84 square meters. Therefore, we can substitute 7 in for b, and 84 in for a.

84=7h

We want to find the height. To do this, we have to get h by itself. Since h is being multiplied by 7, divide both sides by 7.

84/7=7h/7

12=h

So, the height is 12 meters

A piece of cloth is required to completely cover a solid object. The solid object is composed of a hemisphere and a cone surmoun

Otrada [13]

Answer:

▶(B) 463.39 m²

<h3>Step-by-step explanation:</h3>

$\space$

Surface area of hemisphere = 2πr²

=> 2×22/7× (7)² = 308 m²

☯<u>For calculating the surface area of a cone we need to calculate its slant height,</u>

$\sf{ \leadsto \: 1 = \sqrt{49 + 1} = \sqrt{50 \: } m}$

$\space$

$\sf{ \leadsto \: \pi \ r1 = \frac{22}{7} \times 7 \times \sqrt{50} = 463.39 \: {m}^{2} }$

$\: \:$

Hope it helps!

Have a great day! :)
