Answer:
15 cm
Step-by-step explanation:
Circumference of circle= 2πr, where r us the radius of the circle.
Given that the circumference of circle is 60πcm,
60π= 2πr
Divide by 2 on both sides,
15π= πr
Divide by π on both sides,
15= r
Thus, radius of circle= 15cm.
Answer:
18 inches
Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ Ah
where A is the area of the base, and h is the height of the pyramid.
The base is a rectangle. Area of a rectangle is width times length, so:
V = ⅓ wlh
Plugging in values and solving:
1512 = ⅓ w (21) (12)
w = 18
The width of the base is 18 inches.
Answer:
$25.24
Step-by-step explanation:
If Tim earns $45.19 each month multiply by 3 which gives you $135.57 take $211.29 subtract $135.57, you get $75.72 which is the total amount that Tom needs to give. Divide that by 3 and get $25.64 which is the amount Tom needs in 3 months.
$45.19 x 3 = $135.57
$211.29 - $135.57 = $75.72
$75.72/3 = $25.24
139° 10′ This is degree minutes. Convert the minutes to decimal by dividing the minutes by 60.
10/60 = 0.167
So 139° 10′ = 139.167 degrees.
Now convert to radians:
139.167 x pi/180 = 2.429 radians
The answer may be slightly different depending on the rounding of everything.
