A square pyramid has base edge length 6 ft. The slant height of the pyramid is 5 ft. What is the volume of the​ pyramid?

Mathematics

nadya68 [22]4 years ago
6 0

Answer:

V = 60 m3

Step-by-step explanation:

Volume of a square pyramid:

V = (1/3)a2h

Slant Height of a square pyramid:

By the pythagorean theorem we know that

s2 = r2 + h2

since r = a/2

s2 = (1/4)a2 + h2, and

s = √(h2 + (1/4)a2)

This is also the height of a triangle side

A circle has a radius of 12 cm. If the radius of the circle is increased by a factor of 7, how many times larger will the circle
-Dominant- [34]

Answer:

The circumference is also 7 times larger

12 cm radius :2*pi*12= 75.43

12*7=84

84cm radius: 2*pi*84= 528

To check if its indeed 7 times larger: 528/75.43 and you'll get 7

If youre looking for the difference between the two: 528-75.43= 452.57

Suppose you invest $200 a month for 7 years into an account earning 9% compounded monthly. After 7 years, you leave the money, w
never [62]

Answer:

$172,806.37.

Step-by-step explanation:

Total = [ P(1+r/n)^(nt) ] + [ PMT × (((1 + r/n)^(nt) - 1) / (r/n)) ] * (1 + r/n)

is the formula  for the amount left after the first 7 years where the money is deposited at the beginning of each month and P = initial amount,  PMT = monthly payment, r = rate as a decimal and t = time in years.

Total after the first 7 years

=  [ 200(1+0.09/12)^(7*12) ] + [ 200 × (((1 + 009/12)^(7*12) - 1) / (0/09/12) ] * (1 + 0.09/12)

= 374.64 +  (200 * 0.8732019633) / (0.09/12) * (1 + 0.09/12)

= 374.64 + 23485.386 * 1.0075

= $24.036.17

Total after a further 22 years:-

=  24.036.17(1 + 0.09/12)^(12*22)

=  $172,806.37 (answer).
