Mathematics
1 answer:
Serga [27]3 years ago
5 0

Known :

r = 5 cm

θ = 360° - 90° = 270°

Asked :

Arc length of the partial circle = ...?

Answer :

Arc length

=  \frac{θ}{360}  \times 2\pi r \\  =  \frac{270}{360}  \times 2 \times 3.14  \times 5 \\  =  \frac{3}{4}  \times 31.4 \\  =  \frac{3}{4}  \times  \frac{314}{10}  \\  =  \frac{942}{40}  \\  = 23.55 \: cm

So, the arc length of the partial circle is 23,55 cm

A bowl in the shape of a hemisphere has a volume of 144π cubic centimeters. What is the radius of the bowl?
Alla [95]

Answer:

6 = r

Step-by-step explanation:

V = \frac{2}{3}πr³                Use this equation to find the volume of a hemisphere

144π = \frac{2}{3}πr³           Divide both sides by \frac{2}{3}π

216 = r³                 Take the cube root of both sides

6 = r

Find the midpoint of the line segment.
Alik [6]

Answer:

(1, 3)

Step-by-step explanation:

The first endpoint (the one on the left) is (-3, 2). The second endpoint (the one on the right) is (5, 4). To find the midpoint, find the middle of both x and y. To do that, add the values of x and y respectively and divide by 2:

for x-value of midpoint:

(x-value of first endpoint + x-value of second endpoint) / 2

= (-3 + 5) / 2

= 2 / 2

= 1

for y-value of midpoint

(y-value of first endpoint + y-value of second endpoint) / 2

= (2 + 4) / 2

= 6 / 2

= 3
