To find the surface area, use the formula for surface area of a cylinder:
S.A. = 2πrh + 2πr², where r is the radius and h is the height.
The radius and height are given as follows.
r = 5
h = 16
Plug these values into the formula and solve to find the S.A.
S.A. = 2πrh + 2πr²
S.A. = 2π(5)(16) + 2π(5)²
S.A. = 2π80 + 2π25
S.A. = 160π + 50π
S.A. = 210π
Since we are leaving our answer in terms of pi, we don't need to do anything more.
Answer:
S.A. = 210π cm²
Answer:
g=6
Step-by-step explanation:
g=4 and g=5 will be more than 7 but g=6 is less.
Answer: 181.46 square inches
Step-by-step explanation:
Area = pi ˣ r squared
Since the radius (half of diameter) is 7.6 inches, then it should equal to 181.46 square inches.
Answer:
2.36 * 10^13 miles
Step-by-step explanation:
Given that :
Proxima centauri is at a distance of 4.24 light years away from the sun.
Distance in miles of Proxima centauri from the sun ;
1 light year = 5.9 * 10^12 miles
Number of light years from the sun * 5.9 * 10^12
= 4 * (5.9 * 10^12)
= 23.6 * 10^12 miles
= 2.36 * 10^13 miles
B. The y-intercept is 0 so it can't be C or D and the slope is 5/1. How I remember this is rise/run. Hope this helps!
