The explanation is the image attached.
Step-by-step explanation:
great circle = 9
= r^2. --> r = 3 m
Surface area S = 4.r^2 = 36 m^2
Volume V = 4/3.r^3 = 36 m^3
-z = 80
You cannot submit an equation with a negative letter ( -z ) so we have to cancel the negative.
To cancel negatives in the equation, we multiply both sides by -1.
-z * -1 = 80 * -1
z = -80
Answer: z = -80
Interest charged: I=prn=6700*0.135*5 = 4522.50
Total re-payment: 6700+4522.50 = 11 222.50
Answer:
1529.4 m^3
Step-by-step explanation:
We will use the formula V = 1/3*h*B for the volume of the pyramid, where V is volume, h is height, and B is are of the base.
First, since we know h and are looking for V, we need B. To find this, since it has a square base, we multiply b, the base length, by itself. 15.3m * 15.3m = 234.09m^2.
Next, we plug into the formula.
V = 1/3*19.6m*234.09m^2
And simplify:
V= 1/3 * 4,588.164m^3
V= 15.29.3879....
Last, round to the tenth
1529.4 m^3
