Question

The radii of the top and bottom of a
bucket of slant height 13 cm are 9 cm
and 4 cm respectively. The height of
the bucket is
A 12cm
0.5
B 16cm
C 10cm
D 15cm​

Answer 1

Answer:

A) 12 cm

Step-by-step explanation:

We know that

H = √[ l^2 - ( r2 - r1)^2]

H = √[13^2 - (9-4)^2]

H = √[ 169 - 5^2]

H = √[ 169 - 25]

H = √144

H = 12 cm

Answer 2

Answer:

A) 12

Step-by-step explanation:

We know that

H= √{l²-(r2-r1)²}

= √{13²-(9-4)²}

= √{169-5²}

= √{169-25}

= √144

= 12 cm
