Answer:
The answer is 256
.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V =
. However, in this formula, 3 will be used instead of (
).
Next, plug in the information given from the problem, and the formula will look like V =
(3) (
).
Then, solve the equation, and the answer will be 256
.
The probabilities can be calculated using an online calculator or tables, depending on which is more readily available.
QUESTION A

Using calculators, the probability will be:

QUESTION B

Using calculators, the probability will be:

QUESTION C
7 7/8 can be estimated to 8
2 2/11 can be estimated to 2
8 + 2 = 10
7 7/8 = 56+7/8 = 63/8
2 2/11 = 22+2/11 = 24/11
63/8 + 24/11 = 693+192/88 = 10.06
So do you see how similar 10 and 10.06 are to each other? :)
Answer:
-3
Step-by-step explanation:
5+-3 equals 2 because it is technically 5-3.
Answer:
4. 480.38m² 6. 3.35
Step-by-step explanation:
Assuming you're looking for the area of the shaded region, you must first be aware that the entire circle has a 360 angle.
From there. for no. 4:
You subtract 87 from 360 to find the angle of the major arc.
360-87=273
From there you must also know the formula to find the area of a sector which is:
(x/360)×pi×r²
In our case 273 is x and 14.2 is r so
(273/360)×pi×14.2²= 480.38
Do the same steps to find 6
