calculate the length of an arc with subtend the Circle of 60 degree at the centre of a circle of radius 1/2 metre ​

Answers

Answer 1

Answer:

2.612 m

Step-by-step explanation:

circumference = (3.14)(0.5)(2) = 3.14 m

subtend mean to opposite part of 60°, so we're looking for a 360-60 = 300° segment.

so 5/6(3.14) = 2.612 m

The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)

Answers

Answer:

82.97cm^2

Step-by-step explanation:

Given data

Circumference=  131.88 centimeters

We want to find the area of 6/10 part of a circle

Firstly, let us find the area of the circle

We need to get the radius

C= 2πr

131.88= 2*3.142*r

131.88=6.284r

r=  131.88/6.284

r=20.98 cm

Area= πr^2

Area= 3.142*20.98^2

Area= 3.142*440.16

Area= 1382.98cm^2

Hence 6/10 of a 1382.98

=0.06*1382.98

=82.97cm^2

The volume of a cereal box is 264 in3 . If it has a width equal to 3 inches and length of 8 inches, what is the height?

Answers

Answer:

11 inches

Step-by-step explanation:

Volume of a box is:

[tex]l * w * h[/tex]

[tex]8 * 3 * h = 264\\\\24*h=264\\\\\frac{24*h=264}{24} \\\\\boxed{h=11}[/tex]

The height is 11 inches.

Hope this helps.

Volume of the box = LWH.

Let V = 264

264 = (8)(3)(H)

264 = 24H

264 ÷ 24 = H

11 = H

The height of the box is 11 inches.
