Answer:
18.03 cubic feet
Step-by-step explanation:
Hello,
Step 1
find the volume of the sphere when radius= 5 ft

Step 2
find the volume of the sphere when radius= 5.1 ft

Step 3
Compare the Volumes to find the change

the volumen of the sphere with radius = 5.1 is 1.06 times bigger than the first one(r=5)
Now, find the change

change=18.03 cubic feet
Have a great day.
3n ¥ 2 = n ¥ 4
If 3n is cubed
9n you divide 9 by 2 then divide that answer by 4
Correct! lines that have undefined slopes are always parallel to the y-axis as the change in x is 0. A gradient is calculated by the change in y divided by the change in x and anything divided by 0 is referred to as undefined.

Hope that helps sorry if its a bit confusing :)
Answer:
£682.57
Step-by-step explanation:
Dan pays £714.73 a year in his car insurance.
The price was reduced by 4.1%
To find the new cost of the insurance, we simply need to find 4.15% of £714.73 and then subtract that from the initial price of the insurance (£714.73)
4.5% of 714.73 is:
= £32.16
Then, the cost of the insurance now is:
£714.73 - £32.16 = £682.57
The insurance now costs £682.57
