Answer:
1: 64π
2: 49π and 153.86
Step-by-step explanation:
For the first one we know that it has a diameter of 16 which means it has a radius of 8 (half the diameter)
To find the area of a circle use the following formula
π*r² where r is the radius
This means that the first answer is π*8^2
which is 64π
For the second one it's the same deal but the radius is 7
so the answer is 49π
Answer:
[24 -12 6]
7 3 0
Unless you also multiply the bottom, then it's:
[24 -12 6]
42 18 0
Step-by-step explanation:
6 * 4 = 24
6 * -2 = -12
6 * 1 = 6
----------------
6 * 7 = 42
6 * 3 = 18
6 * 0 = 0
1. 5pq =5(4)(-3) = 20(-3) = -60
2. pr+q = (4)(-2) = (-3) = -8 + (-3) = -11
Answer:
0.70
Step-by-step explanation:
The nine is in the hundreths place, and it is over five, so you would round the number to the left of it up (the six). Basically, ignore the 8.
Answer:
706.50 cubic cm.
Step-by-step explanation:
Given that a cylinder shaped juice pitcher has a diameter of 12 cm and a height of 25 cm.
We are to find out the t volume of juice does the pitcher contain when it is 25% full. 3.14 is to be used for pi.
Volume of the cylinder = 
When it is 25% full the volume would be 1/4 of the full volume
=
cubic cm
So volume when 25% full is
706.50 cubic cm.
