What is the volume of a hemisphere with a radius of 6.5 ft, rounded to the
nearest tenth of a cubic foot?
Answer:
Answer:574.9ft^3.
Step-by-step explanation:
radius (r) = 6.5feet
π=3.14
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x (6.5) ^3
Volume=2/3 x 3.14 x 6.5 x 6.5 x 6.5
Volume = (2x3.14x6.5x6.5x6.5) ➗ 3
Volume=1724.645 ➗ 3
Volume=574.9ft^3
The volume of a hemisphere with a radius of 6.5 ft, rounded to the
nearest tenth of a cubic foot is 574.9ft^3.
What is the volume of a hemisphere?The volume of a hemisphere that has radius r can be calculated as
[tex]2/3\times \pi \times r^3[/tex]
It is given that the hemisphere
radius (r) = 6.5feet
π=3.14
The volume of a hemisphere
=[tex]= 2/3\times \pi \times r^3\\\\= 2/3 \times3.14\times (6.5) ^3\\\\2/3 \times3.14 \times6.5 \times6.5 \times6.5\\\\1724.645 /3\\574.9ft^3[/tex]

Find the measure of the complement of an 18° angle.
Answer:
72°
Step-by-step explanation:
Hello There!
Complementary angles have a sum of 90 degrees
So to find the missing angle we subtract the measure of the given angle (18 in this case) from 90
90 - 18 = 72
so your answer will be 72°

Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230. What was her percent of error in her calculations?
Answer:
8.7%
Step-by-step explanation:
the formula for % error is = [ (approx. - exact ) / exact ] x 100
so, we know the approx value was 250 while the exact one is 230
thus; [ ( 250-230 ) / 230 ] x 100
= 8.7%

Her employer's contribution to the 401(k) was $2,500.
CalculusGiven that for the first 3% of Pam's salary, her employer matches 100% of her 401(k) contributions, and from 3% to 12%, Pam's employer matches 50% of her 401(k) contributions, and Pam's salary is $30,000 , and last year, she contributed $4000 to her 401(k) plan, to determine what was her employer's contribution to the 401(k) the following calculation must be made:
4000 / 12 x 3 = X1000 = X(4000 / 12 x 9) / 2 = X3000 / 2 = X1500 = X1000 + 1500 = 2500Therefore, her employer's contribution to the 401(k) was $2,500.
