Answer:
45
Step-by-step explanation:
2/9 = 10/m
m = 10*9/2
m = 90/2
m = 45
Answer:
= 72*pi
If we approximate pi
= 226.08
Step-by-step explanation:
The area of the entire circle is
A = pi * r^2
where r = 24
A = pi * 24^2
A = pi *576
45 degrees is part of a 360 degree circle
45/360 =1/8
Multiply the area by 1/8 since it is 1/8 of the circle
1/8 A = 1/8 * 576pi
= 72*pi
If we approximate pi
= 226.08
Answer:
2.6 x 10^21
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
