The surface area of a sphere is given by

where r represents the radius.
As the radius is given as 60 meters we replace r with 60 in the formula above to get the surface area.
Answer:
second option, IQR = 13-6 = 7 and Range = 17-6 = 11
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
in STR,
ST=SR
therefore, t=r(angles opposite equal sides of a triangle are equal)
T=73
C+73+73=180(ASP of triangle)
C=34
Answer: The price of an adult ticket = $6
The price of a student ticket = $12
Step-by-step explanation:
Let the price of an adult ticket be a
Let the price of a student ticket be b.
From the question,
5a + 14b = 198 ...... equation i
10a + 8b = 156....... equation ii
Multiply equation i by 10
Multiply equation ii by 5
50a + 140b = 1980 ...... equation iii
50a + 40b = 780 ....... equation iv
Subtract iv from iii
100b = 1200
b = 1200/100
b = 12
Put the value of b into equation ii
10a + 8b = 156
10a + 8(12) = 156
10a + 96 = 156
10a = 156-96
10a = 60
a = 6
The price of an adult ticket = $6
The price of a student ticket = $12
