Answer:
Question 1.
a)
b)
Question 2:
Question 3:
Explanation:
Question 1. In the cone below, the radius is 6 meters and the height is 8 meters.
A) Find the exact value of the volume of the cone.
Formula:
Plug in r = 6m, and h = 8m
Solution:
B) Find the approximate value of the volume of the cone rounded to the nearest tenth.
Substitute π with its approximate value 3.14
Question 2. Find the volume of the cylinder pictured below. Use 3.14 for pi. Give your answer rounded to the nearest tenth.
Formula
Plug in diameter = 10 ft, height = 21, and π = 3.14
Solution:
Question 3. Find the volume of the sphere pictured below. The sphere has a radius of 20 cm. Use 3.14 for pi. Give your answer rounded to the nearest tenth.
Formula
Plug in r = 20cm, and π = 3.14
Solution:
Step-by-step explanation:
Answer:
14m
Step-by-step explanation:
Area = πr²
A = 153.86m²
153.86 = 3.14 *r²
r² = 153.86/3.14
r = √49
r = 7
d = 2r
d = 2*7
d = 14
Answer:
269.46
Step-by-step explanation:
sin(theta) = opposite / adjacent
adjacent = opposite / sin(theta)
adjacent = 1425*sin(10.9)
adjacent = 269.4610063
In a parallelogram we know that co-interior angles are supplementary
That is, sum of Angel A and Angle D=180
So , in the given question, it is given that, Angle A=46 and angle D=100
Since , the sum is not 180
=> the answer is false..!!
Hope this helps you!!!
