Answer:
2×2=4
Step-by-step explanation:
Multiplying by powers is the same as multiplying one number by itself
The radius of the circle is 7 which is r in the eq.
put 7 instead of r in the volume of sphere formula.
Then multiply all sides of square which will be 12 x 12 x 12 = 1728
Now add the values from both shapes
1728 + 1436.75
Your answer will be 3163.5 cm(cubed)
Remember you can do anything to an equation as long as you do it to both sides
expand by foiling or distributing
4x²-19x-5=-43x-41
add 43x to both sides and add 41 to both sides
4x²+24x+36=0
factor
facotr out of 4
4(x²+6x+9)=0
factor inside
what 2 numbers multiply to get 9 and add to get 6?
3 and 3
4(x+3)(x+3)=0
set to 0
x+3=0
x=-3
x=-3 is answer
Answer:
95π
Step-by-step explanation:
area of a circle=πr²
radius of the big circle = 24/2=12
area of big circle = π(12)² = 144π
are of small circle = π(7)² = 49π
shaded area = area of big circle - area of small circle
= 144π-49π
= 95π
