Answer:
339.336 m^2
Step-by-step explanation:
Given data
Radius= 6meters
We know that the surface area of a half-sphere is given as
A=3πr^2
A= 3*3.142*6^2
A= 3*3.142*36
A=339.336 m^2
There are 20 skirts in total and five of them are yellow.
The probability that she will pick a yellow skirt is 5/20 (simplifies to 1/4)
Multiply this by the probability that the coin will land on tails 1/2
1/4 x 1/2 =
1/8
Maria has a 1/8 chance that she will pick a yellow skirt AND land the coin on tails.
8^2 + b^2 = 24^2
64 + b^2 = 576
-64 -64
b^2 = 512
Take the square root from b^2 and 512 =
b = 22.627
Answer 22.63 (rounded up)
Answer:
D
Step-by-step explanation:
a and b goes down because are negative power and 25/5 =5.
The complementary angles are two angles whose measures add up to 90. Therefore the measure of the complementary angle is 63.
Because 27 + 63 = 90
