Answer:
√27
Step-by-step explanation:
The triangles of the pyramid are equilateral triangles with sides of 6''.
Dividing a triangle into two equal parts we get two congruent right triangles, with a hypotenuse of 6'', one leg of 3'', and the other leg is the slant height (s). From Pythagorean theorem:
3² + s² = 6²
s² = 6² - 3²
s = √27
Answer:
A. 31.4 in.
Step-by-step explanation:
Formula for the circumference:
C = dπ (d = 2r)
Therefore:
C = 10π
C = 10 · 3.14
C = 31.4 in.
Answer:
A=2πrh+2πr^2
Step-by-step explanation:
If a customer ordered 5 items and the order had a total of 17 wheels, we are to determine the number of wagons that was ordered. A wagon has four wheels, therefore, 17 divided by 4 wheels is equal to 4 r. 1. So, 4 wagons were ordered and one extra wheel to complete the 17 wheels and 5 orders.
