Answer:

71 times

Step-by-step explanation:

Diameter of BMX bike= 0.45m

Radius= 0.225m

Cirumference of BMX bike

C= 2πr

C=2*3.142*0.225

C= 1.4139m

In a 400-m race, the BMX bike will turn

=400/1.4139

=282.9 times

=283 times

Diameter of  Mountain bike= 0.6m

Radius= 0.3m

Circumference of Mountain bike

C= 2πr

C=2*3.142*0.3

C=1.8852m

In a 400-m race, the Mountain bike will turn

=400/1.8852

=212.17 times

=212 times

Hence the difference is

=283 -212

=71 times

a maxicool consists of a cone full of ice cream with a hemisphere of ice cream on top. the radius of a hemisphere is 3cm. The he
Gemiola [76]

According to the information, it can be inferred that the volume of the ice cream is close to 207.33 cm³

<h3>How to calculate the volume of the maxicool?</h3>

To calculate the volume of the maxicool, we must calculate the volume of the sphere of ice cream, and the volume of the cone that is filled with ice cream.

<h3>Volumen of the sphere</h3>

V = \frac{4}{3} × π × R³

V = \frac{4}{3} × π × 3³

V = 113.09 cm³

<h3>Cone volume</h3>

V = \frac{1}{3} × π × R² × <em>h</em>

V = \frac{1}{3} × π × 3² × 10

V= 94.24 cm³

Finally we must add both values to know the total volume of the maxicool.

113.09 + 94.24 = 207.33 cm³

The base and corresponding height of a parallelogram are 75 cm and 25 cm. If the other base is 50 cm, find out its corresponding
aleksandr82 [10.1K]

Answer:

Height of the parallelogram = 37.5 cm

Step-by-step explanation:

As given,

Base of a parallelogram = 75 cm

Height of a parallelogram = 25 cm

As,

we know that

Area = Base × Height

        = 75 × 25

        = 1875 cm²

As the parallelogram is same

So, Area = Base × Height

⇒1875 = 50 × Height

⇒ Height = \frac{1875}{50} = 37.5 cm

So, we get

Height of the parallelogram = 37.5 cm
