Russ is correct hope that helps you
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:
a) y=8
b) x= 9
Step-by-step explanation:
a)
y/16= 2/4
y= 16 * 1/2 (cross multiply)
y= 8
b) x/5 = 36/20
x= 5 * 36/20 (cross multiply)
x= 9
Answer:
About 20%
Step-by-step explanation:
The probability of a point on the un-shaded region will be given by;
Area of the shaded region/total area
Considering that the circles are of the same size, then the length of the square is 2d
Area of the square = 4d²
Area of the shaded = (4d² -4π(d/2)²
= 4d² -πd², but π = 22/7
= 6/7d²
Probability = (6/7d² ÷ 4d²) × 100%
= (6/28 d²) × 100%
= 21.42 %
So your answer is B. 20%
Don't thank me this was easy.
Probability always sums up to 1
P(pizza) + P(cheeseburger) + P( chicken sandwich) + P(caesar salad) + P(macaroni and cheese) = 1
let P(caesar salad) be x
0.2 + 0.45 + 0.06 + x + 0.12 = 1
x= 0.17
