Answer:

310.86 cubic units

Step-by-step explanation:

Volume of a cylinder

= pi r^2 h

Given radius r = 3units

Height = 11 units

Pi = 3.14

Volume = 3.14 x (3)^2 x 11

3.14 x 3x3 x 11

Multiply through

V = 310.86 cubic units

express 121,200 in exponential (powers of 10) notation. express the earth sun distance in kilometers in powers of 10 notation.
Mashutka [201]

The exponential form of given number 121200 is 1.212 × 10^5

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × 10^8

For given question,

We need to express 121,200 in exponential (powers of 10) notation.

To use scientific notation, pick a value between 1 and 10, then multiply it by 10ˣ.

The number between 1 and 10 in 121200 is 1.212 with 5 decimal points.

So, the exponential notation of given number would be,

121,200 = 1.212 × 10^5

Earth's average distance from the Sun is around 93 million miles (150 million kilometers). That's one AU.

So the number between 1 and 10 in 150,000,000 is 1.5, with 8 decimal points.

So, the distance between he Earth and the Sun is:

150,000,000 = 1.5 × 10⁸

Therefore, the exponential form of given number 121200 is 1.212 × 10^5

And the earth sun distance in kilometers in powers of 10 notation is 1.5 × 10^8

Find the area of this figure to the nearest hundredth. Use 3.14 to approximate pi.
Fantom [35]

Answer:

49.12 square units

Step-by-step explanation:

Area of triangle = \dfrac{1}{2}*base *height

                          =\dfrac{1}{2}*6*8=3*8 = 24 \ sq.units

Circle:

d = 8 units

r = 8/2 = 4 units

Area \ of \  semicircle = \dfrac{1}{2}\pi r^{2}\\

                                =\dfrac{1}{2}*3.14*4*4=3.14*2*4= 25.12 \ sq.units

Area of the figure = area of triangle +area of semicircle

   = 24 + 25.12

    = 49.12 sq. units
