Area of a circle is
. The first one, a, the radius squared is 8*8=64. So
. If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So
square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So
. Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore,
, or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!
Answer:
A:
Misaki had 2 identical pencils that weighed a total of 19 grams, where x is the number of pencils and y is the total weight of the pencils.
Step-by-step explanation:
One of the points is 2 and 19, 2 is along the x axis and 19 is along the y axis
80% × x = 32
.80x = 32
x = 32/.8
x = 40
Answer:
100/9
Step-by-step explanation:
(7*5*2/7*3)² * (5^0/2^-3)³ * 2^-9
Solution:
We know that any number with power 0 = 1
(7*5*2/7*3)² * (1/2^-3)³ * 2^-9
Now cancel out 2 by 2
= (7*5*2/7*3)² * (1/1^-3)³ * 1^-9
=(70/21)² * (1)³/(1^-3)³ * 1^-9
=(10/3)^2 * 1/1^-1 * 1/1^9
=100/9 *1 *1
=100/9....
It should be 23/99
23/99= 0.232323...
23/999= 0.023023023....
2/9= 0.222222....
Final answer: 23/99
