Work out the volume of this sphere.
navik [9.2K]

Answer:

Volume of the sphere ( V ) = 1436.02 cm³

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the radius of the sphere r = 7 cm

Volume of the sphere

                  V = \frac{4}{3} \pi r^{3}

                 V = \frac{4}{3} \pi (7)^{3}

                 V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02

                 V = 1436.02 cm³

Volume of the sphere

                  V = 1436.02 cm³

saw5 [17]

Answer:

$4,500

Step-by-step explanation:

For simple interest,

I = prt,

where

I = interest

p = principal

r = annual interest rate

t = number of years

We have p = $5,000, r = 9% = 0.09; t = 1 year

I = $5,000 × 0.09 × 1

I = $450

A circular flower bed is 19 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk
yaroslaw [1]

Answer:

289 m²

Step-by-step explanation:

First find the area of the flower bed

A=πr²= (3.14)(9.5)² = 283.385

Then get the area of everything including the sidewalk

A=πr²= (3.14)(13.5)² = 572.265

Then subtract and you'll get the area of just the sidewalk

572.265 - 283.385 = 288.88m²

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 3 . If there were
Alchen [17]

Answer:

There were 2747 yes votes.

Step-by-step explanation:

This question can be solved using proportions.

The ratio of yes votes to no votes was 5 to 3 .

This means that for each 5 + 3 = 8 votes, 5 were yes and 3 were no.

If there were 4395 total votes, how many yes votes were there?

For each 8 votes, we have 5 yes. How many yes votes were there in 4395 votes?

5 yes - 8 votes

x yes - 4395 votes

8x = 4395*5

x = 4395*5/8

x = 2747

There were 2747 yes votes.
