Answer:
Total Surface Area of Solid = C.s.a of hemisphere+C.s.a of cone+C.s.a of Cylinder
slant height of cone=√h²+r²
=√6²+8²
=√100
=10cm
height of cone = 10 cm
radius of hemisphere =radius of cone=radius of cylinder=8cm
T.S.A of solid=2πrh+2πr²+πrl
=πr[2h+2r+l]
=3.14*8[2*10+2*8+10]
=25.12[36+10]
=25.12*46
=1155.52 cm²

Explanation: But Africans had their particular system of recording past events, situations, and traditions before Europeans started writing about it. This is based on collecting oral testimonies. As a result, Non-African historians used written documentation to chart the history of the continent.
Answer:
2.
a)rock phosphate
b)organic compost
c)synthetic fertilisers
d)bone meal
3.
a)increase root development, and produce flowers.
b)feed microorganisms
Explanation:
Rock phosphate – a slower acting source where the soil needs to convert the rock phosphate into phosphorous that the plants can use.
synthetic Fertilizers – applying a fertilizer with high phosphorous
Organic compost – adding quality organic compost to your soil will help increase phosphoos content
Bone meal – a fast acting source that is made from ground animal bones which is rich in phosphorous.
Answer:
Extinction.
Explanation:
Extinction is a process of weakening the appropriate behavior of the person as he/she behaved previously.
Kathy's teacher didn't teach her not to behave like this and ultimately she increased her way of behaving towards the classmates which are called Extinction.
For example, if we are teaching our dog to shake hands with the people but after some time if we are not admiring him or else we are stopping to ask for the shake hand, we are weakening his way of conditioned behavior.
So finally Extinction stops us to make improvements in our unusual behavior.
