The volume of the pyramid is $726 \mathrm\ {cm}^{3}$

Explanation:

The height of the square pyramid is 18 cm

The base of the square pyramid is 11 cm

The volume of the square pyramid can be determined using the formula,

$V=\frac{1}{3} b^{2} h$

Substituting b=11 and h=18 in the formula, we have,

$V=\frac{1}{3} (11)^{2} (18)$

Simplifying, we have,

$V=\frac{1}{3} (121)(18)$

Multiplying, we get,

V=\frac{2178}{3}

Dividing, we get,

V=726 \ cm^3

Thus, the volume of the pyramid is $726 \mathrm\ {cm}^{3}$

The ratio of angle measures is 1:2:2. Classify the triangle by its angle measures. a.acute triangle b.right triangle c. obtuse t
HACTEHA [7]
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
