Orlov [11]

<h3>given:</h3>

base= 25 mm

height= 28 mm

the volume of the square pyramid.

<h3>solution:</h3>

$volume = {a}^{2} \frac{h}{3}$

$v = {25}^{2} \frac{28}{3}$

$v = 5833.33333 {mm}^{3}$

$v = 5833.3 {mm}^{3}$

HELP ME PLZZZZ!!!!!!!!!!!!!!!!!!

Alekssandra [29.7K]

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486

A car travels 370 1/2 miles in 6 1/2 hours what is the average speed at which the car is traveling

Alex

Answer:

57 miles per hour

Step-by-step explanation:

Speed is equal to distance over time

I changed the fractions to decimals for ease of math

distance = 370 .5 miles

time = 6.5 hours

Speed = 370.5/6.5 = 57 miles/hour
