Question

volume=1200m Height=40m find base.​

Answer 1

Step-by-step explanation:

if base is a , the formula is =1/2* base* height

so, 1/2*a*40=1200

or, a=1200* 2 /40=60

so, the base is 60m

Answer 2

Answer :

★ Nothing is given , so we presume it is cylinder and solve further .

• Volume of cylinder = πr²h

Now , here , Volume = 1200 m and Height = 40 m

★ Substituting the values :

$\leadsto \sf Radius\:=\: \sqrt{ \dfrac{V}{πh}}$

$\leadsto \sf Radius\:=\: \sqrt{ \dfrac{1200 \times 7}{22 \times 40}}$

$\leadsto \sf Radius\:=\: \sqrt{ \dfrac{</p><p>8400}{880}}$

$\leadsto \sf Radius\:=\: \sqrt{9.54}$

$\leadsto \large \sf Radius\:=\: 3.08\:m$

• Base = 2 × Radius = 2 × 3.08 = 6.16 m

★ Base = 6.16 m
