you know you can just use a calculator or a search engine for that, right?
Answer:
10.5 cm^2
Step-by-step explanation:
Area of a triangle = 1/2(L x H)
Reading from the diagram
length = 7 cm
height = 3 cm
therefore
Area of the triangle = 1/2( 7×3)
Area = 10.5 cm^2
Answer:
Matt's Answer.
Step-by-step explanation:
Note that in the equation, you need a radius (r). However, a <em>diameter is given, which is 15 centimeters</em>. This means that, to solve this equation, you must first divide 15 by 2, to be able to continue to solve. In Matt's case, he failed to do that.

Volume of Sphere=4/3.pi.r^3
Volume of Cone=1/3.pi.r^2.h
4/3.pi.r^3=1/3.pi.r^2.h
4.r=h
