B 1436.03 cm3
C 1975.43 cm3
D 11,494.04 cm3
Answer:
b
Step-by-step explanation:
Answer:
B. 1436.03 cm^3
Step-by-step explanation:
What you do is use the formula of the volume of a sphere which is
v=4/3*3.14*r^3.
The r represents radius and the radius is 7 which is half the diameter.
So you will plug 7 into the formula.
V=4/3*3.14*7^3.
V=1436.03 cm^3 which is your answer.

Answer:
The answer to 2 1/4 X 3 1/3 is 7 1/2
(A) 4 mph
(B) 5 mph
(C) 6 mph
(D) 30 mph
Answer:
(C) 6 mph
Step-by-step explanation:
Given,
The time taken by Tobin = 30 minutes,
While, the time taken by her opponent = 45 minutes,
So, the ratio of the time taken by tobin and her opponent = 30 : 45
Thus, the ratio of speed of tobin and her opponent =
= 45 : 30
= 3 : 2
Suppose speed of tobin = 3x and speed of opponent = 2x
Where, x is positive real number,
Difference in speed = 3x - 2x = x
According to the question,
x = 2 miles per hour,
Hence, the speed of Tobin = 3x = 6 miles per hour.
Option (C) is correct
Answer:
6844DVDs
Step-by-step explanation:
At the start of the day, there are 78boxes in the warehouse and each box contains 116DVDs, the total number of DVDs in the warehouse will be total number of DVDs per box × number of DVDs in each box;
No of DVDs in the warehouse = 78×116
= 9048DVDs
If 19boxes of DVD were shipped, the total number of DVDs shipped will be 19×116(remember there are 116DVDs in a box)
= 2204DVDs
To calculate the amount of DVDs left in the House, we will use the expression;
Total number of DVDs in the warehouse - total number of DVDs shipped
= 9048-2204
= 6844DVDs
Answer: 832 cm².
Step-by-step explanation:
1. To calculate the lateral area of the prism by using the net you must:
- Calculate the perimeter of the base:
Where l is the lenght and w is the width:
Then:
- Now you must multiply the perimeter by the height. The height is 13 cm.
Then, the lateral surface area is:
