Answer: height = 13.9 cm
Step-by-step explanation:
The base area of a cone is the area of a circle. Given that base area = 98.56 cm^2
Base area = πr^2
Substitutes the value into the formula
98.56 = 22/7 × r^2
Cross multiply
689.92 = 22r^2
r^2 = 689.92/22
r = sqrt ( 31.36 )
r = 5.6 cm
Also, the curved surface area of a cone is πrL
Where the given value is 264 cm^2
Substitutes the value into the formula
264 = 22/7 × 5.6 × L
Where L = slant height
Cross multiply
123.2L = 1848
L = 1848 /123.2
L = 15 cm.
Using pythagorean theorem to find the height H of the cone.
H^2 = L^2 - r^2
H^2 = 15^2 - 5.6^2
H = sqrt( 193.64 )
H = 13.9 cm
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Large eggs : ≥2 ounces
Mean of 48 large eggs = 2.1 ounces
Mean absolute deviation = 0.08 ounces
0.08 ounces here is the mean absolute deviation of the 48 large eggs weighed, meaning that:
The average of the sum of the absolute differences in each individual egg and the mean value of all eggs weighed is 0.08.
This means that the average difference, variability or deviation in the weight of large eggs weighed is 0.08 ounces around the mean value of all eggs weighed.
Mean Absolute Deviation (MAD) :
Σ|xi - mean| / n
xi = each individual value
n = number of values
