Step-by-step explanation:
SURFACE AREA of a cylinder is 2×pi×r×(h+r)
=> 2×3.14×7×(8+7)
=>43.96×(15)
=>659.4 mm^2
Answer: 810
Step-by-step explanation:
first lets take down the information we were given,
height (h) of the pyramid should be 12 - 9 = 3
base (a) = 9
So we calculate the volume of a square pyramid
V = a²h/3
V = (9² × 3) / 3
v = (81 × 3) / 3
V = 81
now we calculate the volume of the cube using the formula
V = a³
V = 9³
V = 729
NOW to get the volume of the entire figure
we say
volume of square pyramid + volume of cube
81 + 729 = 810
Answer:
a = 
Step-by-step explanation:
4(2a + 2) = 8(2 - 3a)
Distribute.
8a + 4 = 16 - 24a
Add 24a to each side.
32a + 4 = 16
Subtract 4 from each side.
32a = 12
Divide 32 from each side.
a = 
Answer:
<u>S2</u>
1. P is represented by -7
2. 1/2
Step-by-step explanation:
1. The P dot is right on the -7 mark, therefore, the number is -7

Answer: <em>3</em>
Step-by-step explanation:
<em>Take your equation x-1=2</em>
<em>Now put 3 in for x</em>
<em>3-1=2</em>
<em>2=2</em>
<em>x=3</em>
