3/4 plus 3/4 equals 6/4 which simplifies to 1 1/2 so draw one full pizza and another half of a pizza
Answer:
The answer is
<h2>1520.5 cm²</h2>
Step-by-step explanation:
Surface area of a sphere is given by
S = 4πr²
where r is the radius
From the question r = 11cm
So the surface area of the sphere is
4π(11)²
= 4(121)π
= 484π
= 1520.5308
Which is
1520.5 cm² to the nearest tenth

Let ‘s’ be the son’s age 12 years ago.
Let ‘f’ be the father’s current age.
4 years ago, the son was:
s-4
So, his father is currently:
3(s-4)
=
3s-12
Therefore:
f = 3s-12
In twelve years, the son will be:
s+12
And the father will be:
f+12
This can also be written as:
3s-12+12 as the fathers younger age would be f = 3s+12
=
3s
So, we know that s+12 is half the fathers current age, meaning the father is currently 2(s+12) which is equivalent to 2s+24. Also, we know that the father is currently 3 times the sons age 12 years ago, so 3s (proven by the calculations we made above). Therefore, 2s+24=3s which means 24=s. We can then substitute this, and we will receive 24+12 = 36
Son’s current age: 36
We then substitute the son’s age 12 years ago into 2s+24 to give us the father’s age.
2(24)+24 = 72
Father’s current age: 72
