Just create a problem and figure it out.
Let's say the original diameter is 4. This means the radius is 4/2 = 2.
A = 2πr^2
A = 2π(2)^2
A = 2π(4)
A = 8π
The new diameter is 50% larger than the original.
50% of 4 is 2. 2 + 4 = 6. So the new diameter is 6. The radius is 6/2 = 3.
A = 2πr^2
A = 2π(3)^2
A = 2π(9)
A = 18π
Old area was 8π, new area is 18π. Now divide the difference from the original area:
18π - 8π = 10π
10π/8π = 1.25 * 100 = 125%
Answer:
56 baseball's? I'm kinda confused twice as many baseball's or what? in any case 28 twice is 56.
Answer: 3.1 cm
Step-by-step explanation:isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
answer is base=3.1 cm
Answer:
x < 8.
Step-by-step explanation:
-5(x+1) > -45
dividing both sides by -5 gives:
(x+1) < 9
NB: the sign changes to it's opposite.
x+1 < 9
subtracting 1 from both sides gives:
x < 8.
