Answer:

See Below:

Step-by-step explanation:

40,000*8/25= the diameter, because the diameter is 8/25 of the equator which is 40000

Diameter= 40,000*8/25

Diameter= 12,800 km

Step-by-step explanation:

Total concrete for slabs

24 * 24 * 1 = 576 ft³

Additional 20 %

By rule of three

if 576 ⇒ 100

x?? ⇒ 20 x = 115,2

And there are 2 slabs, the total volume of concrete is:

Q(t) = 2* (576 + 115,2 ) Q(t) = 1382,4 ft³ (1)

If the truck can carry a maximum of 8 yd³, as 1 ft³ = 0,037 yd³

then a truck can carry a maximum of

8/ 0,037 = 216,21 ft³

Now the total quantity is 1382,4

Then

1382,4/216,21 = 6,39

And as nobody can send a fraction of a truck , the fewest number of truck is 7

Hi again here's the picture

Answer:

<h2>351.88 m</h2>

Step-by-step explanation:

Given,

D = diameter of semicircular part = 42 m

L = Length of straight part = 110 m

Now, let's find the perimeter:

= 2 ( length of semi-circle + length of straight part )

$= 2( \frac{\pi \: d}{2} + l)$

Plug the values

$= 2( \frac{3.14 \times 42}{2} + 110)$

Calculate the product

$= 2( \frac{131.88}{2} + 110)$

Divide

$= 2 (65.94 + 110)$

Calculate the sum

$= 2 \times 175.94$

Calculate

$= 351.88 \: m$

Hope this helps..

Best regards!!
