1 answer:
Answer:
9852 Rounded to the nearest whole number.
Step-by-step explanation:
C = 2
r Fill in what we know to solve for r
176 = 2r Divide both side by 2
r = 28 rounded to the nearest whole number.
The formula for the area of a circle is
A = 4
A = 4
A = 9852 Rounded to the nearest whole number

Step-by-step explanation:
Volume of pot = πr²h
= 3.14 * 10 * 10 * 20
= 6280 cubic cm
1000 cubic cm = 1 litre
6280 cubic cm = 6.28 litre
∵ 2.5 litres will fit in the pot as the capacity of pot is 6.28 litre
Answer:
(3x+4b)(a-2y)
Step-by-step explanation:
(3ax-6xy)+(8by-4ab)

(3x+4b) (a-2y)
Answer:
Likely
Step-by-step explanation:
There are only 2 odd numbers so you’re more likely to get an even number than an odd one.
Answer:
Step-by-step explanation:
Y = mx + b
-1/2 x + 3y = -3
3y = 1/2 x -3
y = 1/6 x - 1
Where slope m = 1/ 6and y intercept b = -1
