Answer:
-24 feet.
Step-by-step explanation:
To find this, we need to multiply -8 and 3. This gets us -24. That means the coral reef is -24 feet. I hope this helps!
Answer:
158,254.08 ft²
Step-by-step explanation:
A nonagon is a polygon with 9 sides and 9 angles. A regular nonagon has all equal sides and all equal angles. In order to find the area of a nonagon, you can use the formula:
A = where 'a' represents the length of one side
Calculating the known measurements ahead of time, we get a condensed, or simplified formula:
A = 6.1818 x a²
Using the side length of 160 ft:
A = 6.1818 x 160² = 158,254.08 ft²
Answer:
2623.6144m²
Step-by-step explanation:
Total Surface Area of a Square Pyramid
a * (a + √(a² + 4h²))
where,
a = area of base
h = height
Using the formula above
a * (a + √(a² + 4h²))
data given :
a = 36
h = 4
a * (a + √(a² + 4h²))
T.S.A. = a * (a + √(a² + 4h²))
Inputting values
T.S.A. = 36 * (36 + √(36² + 4 * 4²))
T.S.A. = 36 * (36 + √(36² + 4 * 16))
T.S.A. = 36 * (36 + √(36² + 64))
T.S.A. = 36 * (36 + √(1296 + 64))
T.S.A. = 36 * (36 + √(1360))
T.S.A. = 36 * (36 + 36.87817782917154)
T.S.A. = 36 * (72.87817782917154)
T.S.A. = 36 * 72.8782
T.S.A. = 2623.614401850175
Therefore Total Surface Area (T.S.A.) is 2623.6144m²
Answer:
Step 1: Multiply the denominator with the whole number. Step 2: Add the numerator to the product obtained from step 1. Step 3: Write the mixed fraction with the sum obtained from step 2 as the numerator and the denominator of the original fractional part of the mixed fraction.
