the height of an equivalent triangle is 15cm and it's perimeter is 36cm find the area of the triangle​
OlgaM077 [116]

Answer:

The area is 72 cm².

Step-by-step explanation:

Since it is equivalent triangle

h = b

so,

b + b + b (since all sides are equal)= 36 cm

3b = 36 cm

or, b = 36/3

so, b = 12 cm

so

area of triangle = (1/2)×b×h

= (1/2)×12cm×12cm

= 6cm × 12cm

= 72 cm²

If you doubled the radius of a sphere, how would the volume change? A. The volume would double. B. The volume would triple. C. T
Ronch [10]
The volume of a sphere, V = (4/3)(PI)(R^3) Let k = (4/3)(PI) Therefore, V = k (R^3) Let R’ = new radius = 2R V’ =k (R’^3) = k (2R)^3 = 8 k R^3 = 8 V The volume would be eight time the original volume.
